NAME

       explain_strtol_or_die - convert a string to a long integer and report errors

SYNOPSIS

       #include <libexplain/strtol.h>
       long explain_strtol_or_die(const char *nptr, char **endptr, int base);
       long explain_strtol_on_error(const char *nptr, char **endptr, int base))

DESCRIPTION

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

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

       nptr    The nptr, exactly as to be passed to the strtol(3) system call.

       endptr  The endptr, exactly as to be passed to the strtol(3) system call.

       base    The base, exactly as to be passed to the strtol(3) system call.

RETURN VALUE

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

       The explain_strtol_on_error function always  returns  the  value  return  by  the  wrapped
       strtol(3) system call.

EXAMPLE

       The  explain_strtol_or_die  function  is  intended  to be used in a fashion similar to the
       following example:
              long result = explain_strtol_or_die(nptr, endptr, base);
