libssh2_trace_sethandler - set a trace output handler
typedef void (*libssh2_trace_handler_func)(LIBSSH2_SESSION *session,
const char *data,
int libssh2_trace_sethandler(LIBSSH2_SESSION *session,
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.
context can be used to pass arbitrary user defined data back into the
callback when invoked.
Added in libssh2 version 1.2.3
