typedef void (*libssh2_trace_handler_func)(LIBSSH2_SESSION *session,

int libssh2_trace_sethandler(LIBSSH2_SESSION *session,
DESCRIPTIONlibssh2_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.
AVAILABILITYAdded in libssh2 version 1.2.3
