Function Documentation

unsigned long long explain_strtoull_or_die ( const char *  nptr,
char **  endptr,
int  base 
)

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

Parameters:
nptrThe nptr, exactly as to be passed to the strtoull(3) system call.
endptrThe endptr, exactly as to be passed to the strtoull(3) system call.
baseThe base, exactly as to be passed to the strtoull(3) system call.
Returns:
This function only returns on success, see strtoull(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:
 unsigned long long result = explain_strtoull_or_die(nptr, endptr, base);
