Function mapping at run-time

[kris.c]

Guess the best way to explain what I need is through the code itself.

# include<stdio.h>
int func(void);
int pfunc(void);

int pfunc()
{
    int val;
    /* do some work */
    return val;
}

int func()
{
    int ret;
    /* log the start of  event in a file with the time */
    ret = pfunc();
    /* log the end of event in a file with the time */
    return ret;
}

int func()
{
    int ret;
    ret = pfunc();
    return ret;
}

int main()
{ 
     int ret;
     ret = func();
     printf(" return value = %d\n",ref);
     return 0;
}

The main function invokes the func routine. If the user wishes to log the event at which the func routine is called, he sets a global parameter at run-time. Depending on whether the parameter is set or not, the appropriate func routine must be invoked.
Could someone help me out and suggest a way of doing it?

using if statement?

if (globalVar)
{
     ret = pfunc();
}
else
{
     ret = func();
}

Yes?

Why have two functions? It looks like you want to turn logging on and off. Inside pfunc(), check if logging is enabled at the beginning and end, and print the messages if it is.
