NAME

       explain_strdup_or_die - duplicate a string and report errors

SYNOPSIS

       #include <libexplain/strdup.h>
       char *explain_strdup_or_die(const char *data);
       char *explain_strdup_on_error(const char *data);

DESCRIPTION

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

       The explain_strdup_on_error function is  used  to  call  the  strdup(3)
       system  call.  On  failure  an  explanation  will be printed to stderr,
       obtained from the explain_strdup(3) function, but still returns to  the
       caller.

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

RETURN VALUE

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

       The explain_strdup_on_error function always returns the value return by
       the wrapped strdup(3) system call.

EXAMPLE

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