Arguments

bit

Bit number of the bit mask to set.

To avoid overflowing any target CPU and/or compiler’s integer data type, unsigned bit constant 1 is either cast to specified integer data type size or suffixed with long integer modifier, ‘L’. This may still be insufficient for CPUs and/or compilers that support long long integer data types, in which case ‘LL’ integer modifier should be suffixed. However, since almost all 16- and 32-bit CPUs and compilers support long integer data types but many may not support long long integer data types, only long integer data types and modifiers are supported.
