shell program- how many times a function is called
We have a program source C and is required to indicate how many times each function is called from the C program. also print the line number where there is a call.
I've tried something like this:
but for eg. if I give a file that isn't C source it doesn't show the right message.
also I'm not very sure that this is the right way to solve this problem, because it only works for the functions that you read from the keyboard , not for each function that you have in your program.
so if you have other ideas please help.
thank you. and sorry for my bad exprimation.

XInitThreads(3) XLIB FUNCTIONS XInitThreads(3)NAME
XInitThreads, XLockDisplay, XUnlockDisplay - multi-threading support
SYNTAX
Status XInitThreads(void);
void XLockDisplay(Display *display);
void XUnlockDisplay(Display *display);
ARGUMENTS
display Specifies the connection to the X server.
DESCRIPTION
The XInitThreads function initializes Xlib support for concurrent threads. This function must be the first Xlib function a multi-threaded
program calls, and it must complete before any other Xlib call is made. This function returns a nonzero status if initialization was suc-
cessful; otherwise, it returns zero. On systems that do not support threads, this function always returns zero.
It is only necessary to call this function if multiple threads might use Xlib concurrently. If all calls to Xlib functions are protected
by some other access mechanism (for example, a mutual exclusion lock in a toolkit or through explicit client programming), Xlib thread ini-
tialization is not required. It is recommended that single-threaded programs not call this function.
The XLockDisplay function locks out all other threads from using the specified display. Other threads attempting to use the display will
block until the display is unlocked by this thread. Nested calls to XLockDisplay work correctly; the display will not actually be unlocked
until XUnlockDisplay has been called the same number of times as XLockDisplay. This function has no effect unless Xlib was successfully
initialized for threads using XInitThreads.
The XUnlockDisplay function allows other threads to use the specified display again. Any threads that have blocked on the display are
allowed to continue. Nested locking works correctly; if XLockDisplay has been called multiple times by a thread, then XUnlockDisplay must
be called an equal number of times before the display is actually unlocked. This function has no effect unless Xlib was successfully ini-
tialized for threads using XInitThreads.
