Instance Method

scanHexLongLong:

Scans for a long long value from a hexadecimal representation, returning a found value by reference.

Declaration

- (BOOL)scanHexLongLong:(unsigned long long *)result;

Parameters

result

Upon return, contains the scanned value. Contains HUGE_VAL or –HUGE_VAL on overflow.

Return Value

YES if the receiver finds a valid hexadecimal long long representation, otherwise NO. Overflow is considered a valid hexadecimal long long representation.

Discussion

The hexadecimal integer representation may optionally be preceded by 0x or 0X. Skips past excess digits in the case of overflow, so the receiver’s position is past the entire hexadecimal representation.

Invoke this method with NULL as result to simply scan past a hexadecimal long long representation.
