Method Pike.__Backend()->call_out()

Method call_out

array call_out(function(:void) f, float|int delay, mixed ... args)

Description

Make a delayed call to a function.

call_out() places a call to the function f with the argument args in a queue to be called in about delay seconds.

If f returns -1, no other call out or callback will be called by the backend in this round. I.e. `() will return right away. For the main backend that means it will immediately start another round and check files and call outs anew.

Returns

Returns a call_out identifier that identifies this call_out. This value can be sent to eg find_call_out() or remove_call_out().
