| Issue |
We are looking for a way to get the program name of the currently executing process without having to reference argv[0]. The getcmd() function call will return all of the command line parameters with the exception of the program name.
Is this possible?
|
| Solution |
Below is an example of finding the executing processes name without referencing argv[0]:
#include <sys/kernel.h>
#include <sys/psinfo.h>
#include <sys/seginfo.h>
#include <sys/types.h>
#include <stdio.h>
#include <unistd.h>
void main (void)
{
struct _psinfo info;
qnx_psinfo (PROC_PID, 0, &info, 0, 0);
printf ("%sn", info.un.proc.name);
} |
