Usage: b = nxt_port_mmap_get_buf(task, port, size); b->mem.free = nxt_cpymem(b->mem.free, data, size); nxt_port_socket_write(task, port, NXT_PORT_MSG_DATA, -1, 0, b);
Compiler built-ins used, where possible. Necessary configure checks added. New macros: nxt_atomic_or_fetch(ptr, val) nxt_atomic_and_fetch(ptr, val) Syntax and behaviour is similar to __sync_or_and_fetch and __sync_and_and_fetch GCC build-ins.
