Function Documentation

long explain_strtol_or_die ( const char *  nptr,
char **  endptr,
int  base 
)

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).

Parameters:
nptrThe nptr, exactly as to be passed to the strtol(3) system call.
endptrThe endptr, exactly as to be passed to the strtol(3) system call.
baseThe base, exactly as to be passed to the strtol(3) system call.
Returns:
This function only returns on success, see strtol(3) for more information. On failure, prints an explanation and exits, it does not return.
Example:
This function is intended to be used in a fashion similar to the following example:
 long result = explain_strtol_or_die(nptr, endptr, base);
