Programming :: Transmit A File By Source-code To USB Drive?
Jun 1, 2010
I want to find a simple and quick way to permit my application to bring a file located in my file system and write it into an external USB device. I have to use Bulk Transfer Only mode that means to use stream of characters only. I looked through the LibUsb library using it in my IDE I can transmit a string. To transfer a whole file I suppose I've to dodge the file system building a char sequence that permits to recognise a file in the file system and to put it into the usb device.

I'm investigating how to copy a file located in my file system into another device. I googled to find a solution for my case but I didn't find anything. My original problem was to find a way to permit my code to move a file into a USB device. I wonder If is there a way to implement the cp command or some mechanism that permits my code to interact with between the file system on my computer and the second one on USB external driver (FAT32) ?

I've tried to use google to find this, and all I find is M$ SAL and some annotation standard for java, neither of which is anything like what I'm looking for.
I am pouring over someone else's source code, and want to be able to take notes on it, saving those notes in a separate text file that I can grep, open in a text editor, etc. I want each annotation line to include a line number (or range of lines) so it's easy to know what part of the code it refers to.
I could do this by hand, but it would be nice if a program existed to read and write such a file format. It could be similar to Kompare, only with editable notes on one side and source on the other, linked together with colored bands.
Does such a thing exist?
Cosme Zamudio and I are discussing a possible file format and an Android app - [url]

I found on the Internet a rough suggestion to debug code which says to add a line:
An example shows this lists the lines of source that do work.
I do not know where these lines are supposed to go and whether the "notdeadyet" should be a call to a subroutine or what. I only found that "%define" is used to link to external files, so I am confused because what I tried did not work.
(I am unable to use (and learn) any debugging tool for another few weeks and I'd like to progress on this If I can.)

For one of my class projects, we have to analyze a usb keyboard driver source code and be able to understand it and present it to the class. Me and a few other people are working together by breaking up the code into sections so each person can analyze a section of code.Now I've ran into a section of this code that I am a little confused about. It seems fairly simple but I just wanted to double check since I wasn't able to find a solid answer.
Code:
static const unsigned char usb_kbd_keycode[256] = {
0, 0, 0, 0, 30, 48, 46, 32, 18, 33, 34, 35, 23, 36, 37, 38,
[code]....

I want to modify the source of cd (the 'change directory' command) to do a little extra for me, but I can't seem to find the source code anywhere.. maybe I didn't look for it well enough, and googling "source code cd" and variants of that doesn't exactly help... I was wondering if anyone knew where I could find the src?

I have a problem in programing pseudo terminal. In the book APUE (advanced programing in the unix environment) in chapter 15.4: coprocess gives an example of using pipe to operate another program, that provide its input and read its output: Figure 15.18. Figure 15.19 is filter to add two numbers using standard IO. The author said that you must flush the IO buffer in the program which are operated through pipe by another program, however, we cannot add fflush to the source code and re-compile the whole program if we need to use it in another process. It said that pseudo terminal can solve this problem, but I have tried in fedora12 with forkpty call and fail. Source code as follows:
The main process:
Code:
#include "common.h"
#define LINESIZE 256
int main()
{
int fd[2];
pid_t pid;
if( socketpair(AF_UNIX, SOCK_STREAM, 0, fd)<0 ) {
perror("create socket error");
exit(1);
}
int master;
struct termios tm;
if( tcgetattr(STDIN_FILENO, &tm)<0 ) {
perror("tcgetattr error");
exit(3);
}
struct winsize size;
if( ioctl(STDIN_FILENO, TIOCGWINSZ, (char*)&size)<0 ) {
perror("ioctl error");
exit(4);
}
setbuf(stdout, NULL);
pid=forkpty(&master, NULL, &tm, &size);
if( pid<0 ) {
perror("create process error");
exit(2);
}
else if(pid>0) {//parent
close(fd[1]);
char line[LINESIZE];
memset(line, 0, LINESIZE);
while( fgets(line, LINESIZE, stdin)!=NULL ) {
write(fd[0], line, strlen(line));
memset(line, 0, LINESIZE);
int n=read(fd[0], line, LINESIZE);
if(n>=0) line[n]=0;
printf("%s", line);
memset(line, 0, LINESIZE);
}
} else {//child
close(fd[0]);
if( fd[1]!=STDIN_FILENO ) {
if(dup2(fd[1], STDIN_FILENO)!=STDIN_FILENO) {
perror("dup2 error");
exit(1);
}
}
if( fd[1]!=STDOUT_FILENO) {
if(dup2(fd[1], STDOUT_FILENO)!=STDOUT_FILENO) {
perror("dup2 error");
exit(2);
}
}
close(fd[1]);
if(execl("./add", "add", (char*)0)<0) {
perror("exec error");
exit(3);
}
exit(0);
}
//parent
wait(NULL);
return 0;
}
The add program reads a line and get two numbers and return the sum of them.
Code:
#include "common.h"
int main() { int n1, n2;
char line[256];
memset(line, 0, 256);
while( fgets(line, 256, stdin)!=NULL) {
sscanf(line, "%d%d", &n1, &n2);
printf("%d", n1+n2);
fflush(NULL); /*the program does not work without this sentence why?*/
memset(line, 0, 256); } return 0; }

running a java application in a remote site,and I would like to debug the application. I'm using jdb, and, due to network architecture, I can only use jdb do debug in text-mode. To debug in text-mode I use the command: jdb -attach remotesite: port. At this point this is ok. Now I would like to attach the source code to the jdb. I tried the command
jdb -attach remotesite: port ~/src/org/path/file.java
to attach the source code to the remote debug to. But it doesn't work. In jdb, I try the command use ~/src/org/path/file.java but it doesn't work either. How can I attach the source code to the remote debug?

I've never really taken advantage of Linux being open source before but I was wondering how the copy and paste functions look like. So far I have found out that they are handled by the X Window System (by reading this thread).But I don't seem to get much further than that.

I found a strange problem when I use gdb in eclipse to debug. When I step in the program, the register RIP(I'm using x86_64 machine and that's EIP in 32 bit mode) shows correctly but the line stepping in the source code may be far from the correct line. For example, when there is no loop in the source code, the RIP keeps on increasing and the current instruction pointer goes back to several lines back. I'm sure the source code is the right one because I when I checked the memory and local variables after several lines the values are all correct. The source code has many empty lines and does it matters with GDB?

I have a Bash script that runs other bash scripts. If the parent code fails, is there any way for me to also kill the child code?That kills any multiple instances of a script if I run it more than once. Is there any way I can just modify this into something that prevents the child code from running/continuing from running if the parent stops from an error?

I would like to download and show a source of an webpage in stdout, but this is a https page with authentication form, which requires logging in. I tried like this:
Code:
wget -q --no-check-certificate --http-user=USERNAME --http-password=PASSWORD https://webpage.domain.com -O - However, it still downloaded only this login page, not the real webpage. Using the Firefox I can authenticate just fine. Any ideas?

I vaguely remember that there is a way to store instructions for vim in my file (like tabstop width etc). I'm not speaking of settings in vimrc but of storing those settings with in the file to be edited. That way the tabstop has always the right width even if I transfer this file to another computer. However, I can't remember what the magic word is so that vim picks up those settings when loading the file.

I listen to a radio show that broadcasts online a lot named ChatterBox Video Game Radio, and when i e-mailed one of the hosts about retrieving archived shows since the site didn't have any archiving of old shows or a link to it. Alon was nice enough to send me one of their old web pages with a HUGE list of archives but it's only the xml source code of the page. since the page isn't live of course, and because of the how he had to send me the code for the page and not a hyperlink to the page, i have the source code. now going through the source code of the page he emailed to me, i can find links to .mp3 files and i can open them and listen to the shows in web browsers, but i was hoping to save them to my computer forfuturelistening.URL]ww.chatterbox'ssite.com/whatever/anotherfolder/showiwanttosave.mp3 in firefox quicktime comes in and lets me listen (as long as my internet connection is active) but wont enable me to save because i dont have the pro version of quicktime. quicktime is good, but i dont use it enough to actually buy the product, and i'm not going to buy the product for just a one time use. is there another way to where i can save this file using the address from the source code (and the ChatterBox allows listeners to save their shows to computer for free, so it not some work around to rob them of money. i fully support them) without having to buy quicktime 7 pro(a product i never really use)?

I had Ubuntu for awhile, now I installed Fedora12, I'm trying to follow directions to install a program from source code (tar.gz file) I have the February 2010 issue of Linux Format, and am trying to follow it step by step. I copied gnurobbo off their disk to my desk top, which copied it. Then I did the cd command, then I did the ls command and it didn't show me anything but a line saying desktop and a few other things like pictures movies etc. so I did cd gnurobbo-0.64 and it says no such file. I have been trying this for a few times and I think I'm going crazy.
