NAME¶atomic_max - atomic_max functions.
int atomic_max(volatile global(3clc) int *p, int val);
unsigned int atomic_max(volatile global(3clc) unsigned int *p, unsigned int val);
int atomic_max(volatile local(3clc) int *p, int val);
unsigned int atomic_max(volatile local(3clc) unsigned int *p, unsigned int val);
DESCRIPTION¶Read the 32-bit value (referred to as old) stored at location pointed by p. Compute commonMax(3clc) (old, val) and store result at location pointed by p. The function returns old.
A 64-bit version of this function, atom_max(3clc), is enabled by cl_khr_int64_extended_atomics(3clc).
