SYNOPSIS

9       #include <libexplain/execlp.h>

DESCRIPTION

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

RETURN VALUE

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.
