# DESCRIPTION
|
||
|
|
|
||

|
|
This callback is used for wildcard matching.
|
||
|
|
|
||
|
|
Return *CURL_FNMATCHFUNC_MATCH* if pattern matches the string,
|
||
|
|
*CURL_FNMATCHFUNC_NOMATCH* if not or *CURL_FNMATCHFUNC_FAIL* if an
|
||
|
|
error occurred.
|
||
|
|
|
||
|
|
# DEFAULT
|
||
|
|
|
||
