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
will create it.
Here is one possible solution if you want to save the file:
Code:
mv Big_File Save_Big_File

If you do not want to save:
Code:
tail Big_File > Big_File

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. SEE ALSO
