NAME ck_pr_bts_ptr, ck_pr_bts_uint, ck_pr_bts_int, ck_pr_bts_64, ck_pr_bts_32, ck_pr_bts_16 -- atomic bit test-and-set operations LIBRARY Concurrency Kit (libck, -lck) SYNOPSIS #include <ck_pr.h> bool ck_pr_bts_ptr(void *target, unsigned int bit_index); bool ck_pr_bts_uint(uint *target, unsigned int bit_index); bool ck_pr_bts_int(int *target, unsigned int bit_index); bool ck_pr_bts_64(uint64_t *target, unsigned int bit_index); bool ck_pr_bts_32(uint32_t *target, unsigned int bit_index); bool ck_pr_bts_16(uint16_t *target, unsigned int bit_index); DESCRIPTION The ck_pr_bts(3) family of functions atomically fetch the value of the bit in target at index bit_index and set that bit to 1. RETURN VALUES This family of functions returns the original value of the bit at offset bit_index that is in the value pointed to by target.
