NAME¶
ck_pr_btc_ptr,
ck_pr_btc_uint,
ck_pr_btc_int,
ck_pr_btc_64,
ck_pr_btc_32,
ck_pr_btc_16 —
atomic bit test-and-complement operations
LIBRARY¶
Concurrency Kit (libck, -lck)
SYNOPSIS¶
#include
<ck_pr.h>
bool
ck_pr_btc_ptr(
void
*target,
unsigned int
bit_index);
bool
ck_pr_btc_uint(
uint
*target,
unsigned int
bit_index);
bool
ck_pr_btc_int(
int
*target,
unsigned int
bit_index);
bool
ck_pr_btc_64(
uint64_t
*target,
unsigned int
bit_index);
bool
ck_pr_btc_32(
uint32_t
*target,
unsigned int
bit_index);
bool
ck_pr_btc_16(
uint16_t
*target,
unsigned int
bit_index);
DESCRIPTION¶
The
ck_pr_btc(
3)
family of functions atomically fetch the value of the bit in
target at index
bit_index and set that bit to its complement.
RETURN VALUES¶
These family of functions return the original value of the bit at offset
bit_index that is in the value pointed to by
target.
