14 The explain_execlp_or_die function is used to call the execlp(3) system
15 call. On failure an explanation will be printed to stderr, obtained
16 from the explain_execlp(3) function, and then the process terminates by
17 calling exit(EXIT_FAILURE).
18
19 The explain_execlp_on_error function is used to call the execlp(3) sys‐
20 tem call. On failure an explanation will be printed to stderr, obtained
21 from the explain_execlp(3) function, but still returns to the caller.
22
24 The explain_execlp_or_die function only returns on success, see exe‐
25 clp(3) for more information. On failure, prints an explanation and
26 exits, it does not return.
27
28 The explain_execlp_on_error function always returns the value return by
29 the wrapped execlp(3) system call.
30
32 The explain_execlp_or_die function is intended to be used in a fashion
33 similar to the following example:
34 explain_execlp_or_die();
35
37 execlp(3)
38 execute a file
39
40 explain_execlp(3)
