execvp() -- General Function (libc)

Execute a load module
#include <unistd.h>
execvp(file, argv)
char *file, *argv[];

The function execvp() calls the  COHERENT system call execve() to execute a
program.   It specifies  arguments as  a  single, NULL-terminated  array of
parameters, called argv. Unlike the related call execv(), execvp() searches
for  file in  all of  the directories named  in the  environmental variable
PATH. For more information on program execution, see execution.

Diagnostics

execvp() does not return if successful.   It returns -1 for errors, such as
file being  nonexistent, not accessible  with execute permission,  having a
bad format, or too large to fit in memory.
