libssh2_trace_sethandler - set a trace output handler
SYNOPSIS
#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);
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 lib-
ssh2_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.

libssh2_session_block_directions - get directions to wait for
SYNOPSIS
#include <libssh2.h>
int libssh2_session_block_directions(LIBSSH2_SESSION *session);
DESCRIPTION
session - Session instance as returned by libssh2_session_init_ex(3)
When any of libssh2 functions return LIBSSH2_ERROR_EAGAIN an application should wait for the socket to have data available for reading or
writing. Depending on the return value of libssh2_session_block_directions(3) an application should wait for read, write or both.
RETURN VALUE
Returns the set of directions as a binary mask. Can be a combination of:
LIBSSH2_SESSION_BLOCK_INBOUND: Inbound direction blocked.
LIBSSH2_SESSION_BLOCK_OUTBOUND: Outbound direction blocked.
Application should wait for data to be available for socket prior to calling a libssh2 function again. If LIBSSH2_SESSION_BLOCK_INBOUND is
set select should contain the session socket in readfds set. Correspondingly in case of LIBSSH2_SESSION_BLOCK_OUTBOUND writefds set should
contain the socket.
