NAME

explain_vfork_or_die - create a child process and report errors  

SYNOPSIS

#include <libexplain/vfork.h>

pid_t explain_vfork_or_die(void);
pid_t explain_vfork_on_error(void);  

DESCRIPTION

The explain_vfork_or_die function is used to call the vfork(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_vfork(3) function, and then the process terminates by calling exit(EXIT_FAILURE).

The explain_vfork_on_error function is used to call the vfork(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_vfork(3) function, but still returns to the caller.  

RETURN VALUE

The explain_vfork_or_die function only returns on success, see vfork(2) for more information. On failure, prints an explanation and exits, it does not return.

The explain_vfork_on_error function always returns the value return by the wrapped vfork(2) system call.  

EXAMPLE

The explain_vfork_or_die function is intended to be used in a fashion similar to the following example:
pid_t result = explain_vfork_or_die();
