execvpe() -- General Function (libc)

Execute a load module
execvp(file, argv, env)
char *file, *argv[], *env[];

The function execvpe() calls the COHERENT system call execve() to execute a
program.   It specifies  arguments as  a  single, NULL-terminated  array of
parameters, called  argv. The argument  env is the  address of an  array of
pointers to strings  that define file's environment.  This allows execvpe()
to pass a new environment to the program being executed.

Unlike the related call execv(), execvpe()  searches for file in all of the
directories named in the environmental variable PATH-- that is, the current
PATH, not the one contained within the environmented pointed to by env.

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.

execvpe() is not part of the  SVID specification.  Therefore, it may not be
present on non-COHERENT operating systems.
