From your comment i take it you are aware that the
umask setting is not the filemode itself but rather the complement to it.
Since you didn't tell us anything about the environment (application, the way it is called, ...) there could be one of several reasons which i can only speculate about
:
1) the application might be built that way. The way you can change filemodes (with
chmod) to override
umasks default the application can do the same. See the
fopen() system call.
2) the application might change effective UID/GID. Some applications (i.e. Apache) do this.
3) if the application is called by a script maybe the script itself calls the application with a new user like in
su - otheruser -c application
4) the directory the application creates files in may have one or more sticky bits set so that files are created with different ownerships and/or permissions
I hope this helps.

Hi,
Please, let me know how the umask is working? As per my understanding is aprt from subtracting from 666/777, logical gate operation is performing.

tk_setappname
Tk_SetAppName(3) Tk Library Procedures Tk_SetAppName(3)
__________________________________________________________________________________________________________________________________________________
NAME
Tk_SetAppName - Set the name of an application for 'send' commands
SYNOPSIS
#include <tk.h>
const char *
Tk_SetAppName(tkwin, name)
ARGUMENTS
Tk_Window tkwin (in) Token for window in application. Used only to select a particular application.
const char *name (in) Name under which to register the application.
_________________________________________________________________
DESCRIPTION
Tk_SetAppName associates a name with a given application and records that association on the display containing with the application's main
window. After this procedure has been invoked, other applications on the display will be able to use the send command to invoke operations
in the application. If name is already in use by some other application on the display, then a new name will be generated by appending "
#2" to name; if this name is also in use, the number will be incremented until an unused name is found. The return value from the proce-
dure is a pointer to the name actually used.
If the application already has a name when Tk_SetAppName is called, then the new name replaces the old name.
Tk_SetAppName also adds a send command to the application's interpreter, which can be used to send commands from this application to others
on any of the displays where the application has windows.
The application's name registration persists until the interpreter is deleted or the send command is deleted from interp, at which point
the name is automatically unregistered and the application becomes inaccessible via send. The application can be made accessible again by
calling Tk_SetAppName.
Tk_SetAppName is called automatically by Tk_Init, so applications do not normally need to call it explicitly.
The command tk appname provides Tcl-level access to the functionality of Tk_SetAppName.
