here are three snippets that show how to do it
APPLE
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <unistd.h>
#include <libproc.h>
int main()
{
pid_t pid;
char path[1024];
int RC;
char *cp;
pid = getpid();
RC = proc_pidpath (pid, path, sizeof(path));
if ( RC <= 0 )
{
exit(-1);
}
else
{
cp = strrchr(path,'/');
*cp=0;
printf("path '%s'\n",path ) ;
exit(0);
}
exit(-1);
}
Freebsd
/* FreeBSD
*/
#include <stdio.h>
#include <unistd.h>
int main()
{
char path[1024];
int size;
size = readlink( "/proc/curproc/file", path, sizeof(path)-1);
path[size] = '\0';
printf("***** '%s'\n", path );
return(0);
}
linux
#include <stdio.h>
#include <unistd.h>
int main()
{
char path[1024];
int size;
size = readlink( "/proc/self/exe", path, sizeof(path)-1);
path[size] = '\0';
printf("***** '%s'\n", path );
return(0);
}
