SYNOPSIS


.In 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
