explain_execlp_or_die(3)
Description
The explain_execlp_or_die function is used to call the execlp(3) system call. On failure an explanation
will be printed to stderr, obtained from the explain_execlp(3) function, and then the process terminates
by calling exit(EXIT_FAILURE).
The explain_execlp_on_error function is used to call the execlp(3) system call. On failure an explanation
will be printed to stderr, obtained from the explain_execlp(3) function, but still returns to the caller.
Example
The explain_execlp_or_die function is intended to be used in a fashion similar to the following example:
explain_execlp_or_die();
