Function Documentation

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

The explain_strtoll_on_error function is used to call the strtoll(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_strtoll(3) function.

Parameters:

nptr	The nptr, exactly as to be passed to the strtoll(3) system call.
endptr	The endptr, exactly as to be passed to the strtoll(3) system call.
base	The base, exactly as to be passed to the strtoll(3) system call.

Returns:

The value returned by the wrapped strtoll(3) system call.

Example:

This function is intended to be used in a fashion similar to the following example:

 long long result = explain_strtoll_on_error(nptr, endptr, base);
 if (result < 0)
 {
     ...cope with error
     ...no need to print error message
 }
