Functions

bsf

int bsf(size_t v)

Scans the bits in v starting with bit 0, looking for the first set bit.

bsr

int bsr(size_t v)

Scans the bits in v from the most significant bit to the least significant bit, looking for the first set bit.

bswap

uint bswap(uint v)

Swaps bytes in a 4 byte uint end-to-end, i.e. byte 0 becomes byte 3, byte 1 becomes byte 2, byte 2 becomes byte 1, byte 3 becomes byte 0.

bt

int bt(size_t* p, size_t bitnum)

Tests the bit.

btc

int btc(size_t* p, size_t bitnum)

Tests and complements the bit.

btr

int btr(size_t* p, size_t bitnum)

Tests and resets (sets to 0) the bit.

bts

int bts(size_t* p, size_t bitnum)

Tests and sets the bit.

inp

ubyte inp(uint port_address)

inpl

uint inpl(uint port_address)

inpw

ushort inpw(uint port_address)

Reads I/O port at port_address.

outp

ubyte outp(uint port_address, ubyte value)

outpl

uint outpl(uint port_address, uint value)

outpw

ushort outpw(uint port_address, ushort value)

Writes and returns value to I/O port at port_address.
