.SH DESCRIPTION
|
|
Pass a pointer to your callback function, which should match the prototype
|
|
shown above.
|
|
|
|
\fICURLOPT_DEBUGFUNCTION(3)\fP replaces the standard debug function used when
|
|
\fICURLOPT_VERBOSE(3)\fP is in effect. This callback receives debug
|
|
information, as specified in the \fItype\fP argument. This function must
|
|
return 0. The \fIdata\fP pointed to by the char * passed to this function WILL
|
|
NOT be zero terminated, but will be exactly of the \fIsize\fP as told by the
|
|
\fIsize\fP argument.
|
|
|
|
The \fIuserptr\fP argument is the pointer set with \fICURLOPT_DEBUGDATA(3)\fP.
|
|
|
|
Available curl_infotype values:
|
|
.IP CURLINFO_TEXT
|
|
The data is informational text.
|
|
.IP CURLINFO_HEADER_IN
|
|
The data is header (or header-like) data received from the peer.
|
|
.IP CURLINFO_HEADER_OUT
|
|
The data is header (or header-like) data sent to the peer.
|
|
.IP CURLINFO_DATA_IN
|
|
The data is protocol data received from the peer.
|
|
.IP CURLINFO_DATA_OUT
|
|
The data is protocol data sent to the peer.
|
|
.IP CURLINFO_SSL_DATA_OUT
|
|
