Corona688,

One more stupid question. From your example:
Code:
#include <stdio.h>

int main() {
        char buf[4096];
        char *n=tmpnam(NULL); // Use this as the file name, not tmp_file.

// get the file
... 

        FILE *fp=fopen(n, "r");
        unlink(n);
        // Read a line into 'buf' until we run out of lines
        while(fgets(buf, 4096, fp))
        {
                // Check the contents of 'buf' for what you want
        }
}

How do I get the results of:
Code:
rsync rsync://192.168.3.1/vpnc/test.conf

into the "n" temp file? Forgive me for my stupidity. Also when I attempt to compile my code, its says to use mkstemp

NAME
cddrec - Read Directory Record from CD-ROM directory SYNOPSIS
/usr/bin/cddrec [-s number] [-b] file OPTIONS
Specifies the File Section for which the Directory Record is to be read. The numbering starts with one and can be any whole number. If this option is not used, the last file section of the named file is assumed. Copies the entire Directory Record from a CD-ROM in binary format to standard output. Names a file within the CD-ROM file hierarchy of a mounted CD-ROM File System. DESCRIPTION
The cddrec command reads the Directory Record associated with a file or directory on a mounted CD-ROM and lists its contents on standard output. The output is formatted in a table that contains the name of each field of the Directory Record and the corresponding contents of the entry as recorded on the CD-ROM. Note that the System Use field is not listed because it may contain non-printable characters. Users must have read permission for file in order to execute the command. EXIT STATUS
The following exit values are returned: The command was successful. The named file was not found, or was not within the CD-ROM hierarchy, or access permission was denied. The File Section indicated by file does not exist. SEE ALSO
Functions: cd_cdrec(3), cd_drec(3) cddrec(1)
