SYNOPSIS

In ck_pr.h Ft bool Fn ck_pr_btc_ptr void *target unsigned int bit_index Ft bool Fn ck_pr_btc_uint uint *target unsigned int bit_index Ft bool Fn ck_pr_btc_int int *target unsigned int bit_index Ft bool Fn ck_pr_btc_64 uint64_t *target unsigned int bit_index Ft bool Fn ck_pr_btc_32 uint32_t *target unsigned int bit_index Ft bool Fn ck_pr_btc_16 uint16_t *target unsigned int bit_index

DESCRIPTION

The Fn ck_pr_btc 3 family of functions atomically fetch the value of the bit in Fa target at index Fa bit_index and set that bit to its complement.

RETURN VALUES

These family of functions return the original value of the bit at offset Fa bit_index that is in the value pointed to by Fa target .
