You can use exec*() family for this purpose.

man exec

Here is a little sample:

[mbaris@zion:/tmp/code_temp]$ cat exec.c
#include <unistd.h>
#include <string.h>
#include <errno.h>

int main(void)
{
  if (execl("/bin/sh", "-c", "./script.sh", NULL)=3D=3D-1)
  {
    printf("ERROR: %s\n", strerror(errno));
  }

  return 0;
}


[mbaris@zion:/tmp/code_temp]$ cat script.sh
#!/bin/bash

echo "Fired!";
exit;

[mbaris@zion:/tmp/code_temp]$ gcc -o exec exec.c
[mbaris@zion:/tmp/code_temp]$ ./exec
Fired!
[mbaris@zion:/tmp/code_temp]$
