curl_multi_select

Wait until reading or writing is possible for any cURL multi handle connection

Description

int curl_multi_select(CurlMultiHandle $multi_handle, float $timeout = 1.0)

Blocks the execution of the script until a cURL handle attached to the cURL multi handle would be able to make progress on the next call to curl_multi_exec or until the timeout strikes (whichever comes first).

Parameters

multi_handle

A cURL multi handle returned by curl_multi_init.

timeout

Time, in seconds, to wait for a response from the active cURL multi handle connections.

Return Values

On success, returns the number of active descriptors contained in the descriptor sets. This may be 0 if there was no activity on any of the descriptors. On failure, this function will return -1 on a select failure (from the underlying select() system call).

Changelog
