I create a http client to send data to server. The code :
int main(int argc, char *argv[])
{
int sockfd;
char buffer[1024];
struct sockaddr_in server_addr;
//struct hostent *host;
int portnumber,nbytes;
[Code]...
I wrote a serial port communication program to access a equipment.
int main(void)
{
int fd = 0;
int nread = 0,i = 0,nwrite = 0, tmpread = 0, m = 0, n = 0 ;
[code]....
I think that it is a pity to manage string programming in C. So, I though to create a variadic function (like printf) but it will not print the result on screen but will malloc an string containing all the string passed in parameters.
But because it is be habitual to concatenate more than two strings, I think that someone has already develop this function. Does somebody know if the function I'm looking for already exists in a library?
When sending data over the socket, the sending socket includes 0x00 after each sent byte. I wonder how this can be avoided -- I just want to transfer the data in the tx_buffer as it is.
# ./serv &
[1] 6895
# ./EUG 127.0.0.1
EUG: Data to be transmitted: 0x35 0x32 0x30 0xff 0x03 0x31
EUG: Data - #Bytes transmitted: 6
./serv: Here is the message: '5'

We make everyday a DB Mysql backup on Linux redhat Enterprise. We are using a bash shell script (and putting it in the crontab) to execute it automatically everyday. We added a line to this script telling, once the backup has completed, to find old backup files (stored on hard disk after each backup) older than x days to remove them. We use the find command (search for file type) with the mtime option and in combination with rm command. Everything runs ok but we also want to add some new code to the same line: If find command cannot find anything or fails, for example if it cannot delete file or fails, send the error message (standard error output) to an error file (like error000001 and increasing) and mail the errorxxxx file to an email address for example to admin@companyname.com. What would be the code for this issue to add it to our find command in the same bash shell script??

i have Ubuntu10.10 (kernel-2.6.35-22-generic) installed. struct stat StatBuff;
[Code]...
I have mounted a windows share folder on /mnt. When i gave any directory within /mnt/ to stat function it fails with errorno 75. perror shows "Value too large for defined data type". Example 1 is fail but Example 2 works fine.
I've set the following as my prompt:... can't post the string due to the 15 post rule. how helpful....
Everything looks fine initially.
1- It sets the username and host in back on green text.
2- It then changes to an off-white an prints the command number for the terminal.
3- Next, it prints the working directory.
4- Finally is prints a ">" character and a space. it looks like this (hostname/un edited & image enlarged slightly to make it easier to read.)
The problem occurs when I try to "up arrow" to reuse and/or edit a prior command. It prints the prior command fine, but if I arrow over to edit the command sometimes the first character can not be deleted from displaying
I'd love to post 2 screen-shots I took to show the problem but.. 15 posts?

In the following code, I am trying to define a matrix in CCS (which is equivalent to CSR for a symmetric matrix, right ?) in ARPACK++.
I have installed and patched ARPACK++. (The matrix is not sparse, but still it should not give an error)
[code]...
Why is this so ? I have checked the values of ia and ja by running intel MKl on the matrix to find the CSR (again, CSR=CCS for symmetric matrix, right ?--I am asking this because ARPACK++ uses CCS, not CSR), and the values are the same. Is this some problem of 0 and 1 indexing ? Does ARPACK++ use 1 indexing?
I have some data files that should be distributed with my program. Using dist_pkgdata_DATA in Makefile.am, I get these files installed to /usr/local/data/share/package-name. The problem is that data is read-only, and my program needs to modify it. Playing with dist_sharedstate_DATA, dist_localstate_DATA, dist-data_DATA varibles, I got different installation directories, like /usr/local/com, usr/local/var, but data is always read-only.
How can I distribute modifiable data files with my package? I need some common directory for all users, or maybe local data in a user directory.

View 2 Replies View RelatedI wasn't paying proper attention when adding a repo to yast and need to find the file were the info is saved to delete this. The problem is that whenever i use yast it comes up with an error code saying that it can't find the data for the 'problem' repo. Have tried zypper rm but that comes up with a similar error advising that the data is in a format that was not expected. My thinking is to track the file were the yast repo source details are saved, delete this and then just add the repos that i use back.

View 3 Replies View RelatedI'm probably doing something stupid, but I thought I'd ask here, because I'm stumped. I'm on slackware 12.2, KDE 3.5 and AIR 2.02.When Echofon abruptly stopped linux support, I switched to tweetdeck (v. 0.34.3.2). It worked great, and they recently pushed a new update. I installed it, deleted the ELS directory in ~/.appdata/Adobe/AIR, and it was unable to find any stored data in kwalletmanager. (I got the error that it wasn't able to find any stored data and that AIR isn't installed properly--the error one gets when tweetdeck is started without kwalletmanager running.)
I deleted the entry in kwalletmanager for AIR, deleted the ELS directory again, and restarted it. Same error, and no new entry in kwalletmanager was made. I downgraded to the previous version (0.32.3.2), and it worked perfectly once more.
