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) system 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,
       obtained 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);
