explain_strndup_or_die(3)  Library Functions Manual  explain_strndup_or_die(3)

NAME
       explain_strndup_or_die -	duplicate a string and report errors

SYNOPSIS
       #include	<libexplain/strndup.h>
       char *explain_strndup_or_die(const char *data, size_t data_size);
       char *explain_strndup_on_error(const char *data,	size_t data_size);

DESCRIPTION
       The explain_strndup_or_die function is used to call the strndup(3) sys-
       tem call. On failure an explanation will	be printed to stderr, obtained
       from  the  explain_strndup(3) function, and then	the process terminates
       by calling exit(EXIT_FAILURE).

       The explain_strndup_on_error function is	used to	 call  the  strndup(3)
       system  call.  On failure an explanation	will be	printed	to stderr, ob-
       tained from the explain_strndup(3) function, but	still returns  to  the
       caller.

       data    The  data,  exactly  as	to  be passed to the strndup(3)	system
	       call.

       data_size
	       The data_size, exactly as to be passed to the strndup(3)	system
	       call.

RETURN VALUE
       The  explain_strndup_or_die  function  only  returns  on	 success,  see
       strndup(3) for more information.	On failure, prints an explanation  and
       exits, it does not return.

       The  explain_strndup_on_error  function always returns the value	return
       by the wrapped strndup(3) system	call.

EXAMPLE
       The explain_strndup_or_die function is intended to be used in a fashion
       similar to the following	example:
	      char *result = explain_strndup_or_die(data, data_size);
