Coolbhai,
If the way your application was designed, it is appending to the file
each microsecond, you must take the risk of loosing some data whenever
you refresh the log file.
If you are appending, then if the file does not exist, the append

xcb_change_save_set_checked
xcb_change_save_set(3) XCB Requests xcb_change_save_set(3)NAME
xcb_change_save_set - Changes a client's save set
SYNOPSIS
#include <xcb/xproto.h>
Request function
xcb_void_cookie_t xcb_change_save_set(xcb_connection_t *conn, uint8_t mode, xcb_window_t window);
REQUEST ARGUMENTS
conn The XCB connection to X11.
mode One of the following values:
XCB_SET_MODE_INSERT
TODO: NOT YET DOCUMENTED.
XCB_SET_MODE_DELETE
TODO: NOT YET DOCUMENTED.
Insert to add the specified window to the save set or Delete to delete it from the save set.
window The window to add or delete to/from your save set.
DESCRIPTION
TODO: explain what the save set is for.
This function either adds or removes the specified window to the client's (your application's) save set.
RETURN VALUE
Returns an xcb_void_cookie_t. Errors (if any) have to be handled in the event loop.
If you want to handle errors directly with xcb_request_check instead, use xcb_change_save_set_checked. See xcb-requests(3) for details.
ERRORS
xcb_window_error_t
The specified window does not exist.
xcb_value_error_t
You specified an invalid mode.
xcb_match_error_t
You created the specified window. This does not make sense, you can only add windows created by other clients to your save set.
