c - Function registered by XtAppAddWorkProc is called many times -

-

i've register function work on background below code:

xtappaddworkproc(app, (xtworkproc)notifyentrycallback, (xtpointer)ent);

it wil ok if call function once in task (click on button example). when call twice or more in task, notifyentrycallback called many time (infinity).

i try store xtappaddworkproc use xtremoveworkproc function remove registered function still not work.

i has spent many times on google cannot know why happens. please me resolve it.

finally, find solution. share faces same issue:

the return value in xtworkproc tell system call registered function again or not. in case, notifyentrycallback should return true if don't want called again.
