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);
