SYNOPSIS

In ck_pr.h Ft bool Fn ck_pr_btr_ptr void *target unsigned int bit_index Ft bool Fn ck_pr_btr_uint uint *target unsigned int bit_index Ft bool Fn ck_pr_btr_int int *target unsigned int bit_index Ft bool Fn ck_pr_btr_64 uint64_t *target unsigned int bit_index Ft bool Fn ck_pr_btr_32 uint32_t *target unsigned int bit_index Ft bool Fn ck_pr_btr_16 uint16_t *target unsigned int bit_index

DESCRIPTION

The Fn ck_pr_btr 3 family of functions atomically fetch the value of the bit in Fa target at index Fa bit_index and set that bit to 0.

RETURN VALUES

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