     16 # NAME
     17 
     18 curl_multi_remove_handle - remove an easy handle from a multi session
     19 
     20 # SYNOPSIS
     21 
     22 ~~~c
     23 #include <curl/curl.h>
     24 
     25 CURLMcode curl_multi_remove_handle(CURLM *multi_handle, CURL *easy_handle);
     26 ~~~
     27 
     28 # DESCRIPTION
     29 
     30 Removes a given *easy_handle* from the *multi_handle*. This makes the
     31 specified easy handle be removed from this multi handle's control.
     32 
     33 When the easy handle has been removed from a multi stack, it is again
     34 perfectly legal to invoke curl_easy_perform(3) on this easy handle.
     35 
     36 Removing an easy handle while being in use is perfectly legal and effectively
     37 halts the transfer in progress involving that easy handle. All other easy
     38 handles and transfers remain unaffected.
     39 
     40 It is fine to remove a handle at any time during a transfer, just not from
     41 within any libcurl callback function.
     42 
     43 Removing an easy handle from the multi handle before the corresponding
     44 transfer is complete might cause libcurl to close the connection - if the
     45 state of it and the internal protocol handler deem it necessary. Otherwise
     46 libcurl keeps the connection alive in the connection pool associated with the
     47 multi handle, ready to get reused for a future transfer using this multi
     48 handle.

     75 
     76 This function returns a CURLMcode indicating success or error.
     77 
     78 CURLM_OK (0) means everything was OK, non-zero means an error occurred, see
     79 libcurl-errors(3).
