explain_vfork_or_die(3) 				     Library Functions Manual					   explain_vfork_or_die(3)

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();

       vfork(2)
	       create a child process and block parent

       explain_vfork(3)
