P99_FIFO_POP #define P99_FIFO_POP (   L ) Pop the front element from an atomic FIFO L. This implements a generic interface to an atomic FIFO (First In - First Out) data structure. To use it you just have do some preparatory declarations and add a p99_lifo field to your data structure: P99_DECLARE_STRUCT(myData); P99_POINTER_TYPE(myData); P99_FIFO_DECLARE(myData_ptr); struct myData { ... myData_ptr p99_lifo; ... }; extern P99_FIFO(myData_ptr) head; Now head can be used as the head of a FIFO: myData_ptr el = P99_NEW(myData, \/\* your initializer arguments \*\/); P99_FIFO_APPEND(&head, el); ... for (myData_ptr el = P99_FIFO_POP(&head); el; el = P99_FIFO_POP(&head)) { // do something with el and then free(el); } See also P99_FIFO_CLEAR P99_FIFO P99_FIFO_DECLARE P99_FIFO_APPEND Remarks argument 0 maybe evaluated several times for its type but only once for its value Definition at line 136 of file p99_fifo.h.
