RedHat 9 (Linux i386) - man page for curl_multi_perform (redhat section 3)

curl_multi_perform(3)				    libcurl Manual				curl_multi_perform(3)

NAME
curl_multi_perform - add an easy handle to a multi session
SYNOPSIS
#include <curl/curl.h> CURLMcode curl_multi_perform(CURLM *multi_handle, int *running_handles);
DESCRIPTION
When the app thinks there's data available for the multi_handle, it should call this function to read/write whatever there is to read or write right now. curl_multi_perform() returns as soon as the reads/writes are done. This function does not require that there actually is any data available for reading or that data can be written, it can be called just in case. It will write the number of handles that still transfer data in the second argument's integer-pointer.
RETURN VALUE
CURLMcode type, general libcurl multi interface error code. NOTE that this only returns errors etc regarding the whole multi stack. There might still have occurred prob- lems on invidual transfers even when this function returns OK.
TYPICAL USAGE
Most application will use curl_multi_fdset to get the multi_handle's file descriptors, then it'll wait for action on them using select() and as soon as one or more of them are ready, curl_multi_perform gets called.
