| .SH NAME |
| libssh2_trace_sethandler - set a trace output handler |
| .SH SYNOPSIS |
| .nf |
| #include <libssh2.h> |
| |
| typedef void (*libssh2_trace_handler_func)(LIBSSH2_SESSION *session, |
| void* context, |
| const char *data, |
| size_t length); |
| |
| int libssh2_trace_sethandler(LIBSSH2_SESSION *session, |
| void* context, |
| libssh2_trace_handler_func callback); |
| .SH DESCRIPTION |
| libssh2_trace_sethandler installs a trace output handler for your application. |
| By default, when tracing has been switched on via a call to libssh2_trace(), |
| all output is written to stderr. By calling this method and passing a |
| function pointer that matches the libssh2_trace_handler_func prototype, |
| libssh2 will call back as it generates trace output. This can be used to |
| capture the trace output and put it into a log file or diagnostic window. |
| This function has no effect unless libssh2 was built to support this option, |
| and a typical "release build" might not. |
| |
| \fBcontext\fP can be used to pass arbitrary user defined data back into the callback when invoked. |
| .SH AVAILABILITY |
| Added in libssh2 version 1.2.3 |
