# DESCRIPTION
|
||
|
|
|
||
|
|
Pass a pointer to your callback function, which should match the prototype
|
||
|
|
shown above.
|
||
|
|
|
||
|
|
This function gets called by libcurl as soon as a part of the stream has been
|
||
|
|
transferred (or skipped).
|
||
|
|
|
||
|
|
Return *CURL_CHUNK_END_FUNC_OK* if everything is fine or
|
||
|
|
**CURL_CHUNK_END_FUNC_FAIL** to tell the lib to stop if some error occurred.
|
||
|
|
|

|
|
# DEFAULT
