Interface __BVR

Inline function

#include <ARCH/BT.H>

Description

This function uses the same bitmap format as __BT and similar __B* functions, but it operates only on one long int. It doesn't operate in memory, but it returns a modified version of the word.

This function clears a bit in an unsigned long int and returns the new value.

Arguments

• val — A value in which the bit will be cleared.
• bit — A bit index. The mapping of bits in the unsigned long int is architecture-specific. The bit argument must be in the range 0 – sizeof(long) * 8 - 1.

Returns

A value val with the bit cleared.
