[sachin sharma]

yes u can do in c using the pragma Directive


there are two directive that allowes u to runyour function before the call
to main or termination of the main
1) #pragma startup
2) #pragma exit



implementation:

void beforemain();
void aftermain();


#pragma  startup beforemain
#pragma  startup aftermain



int main()
{
       printf("\ni  m inside main\n");
        return 0;
}



void beforemain()
{
        printf("\ni m before the main and is executing.........!!!\n");
}



void aftermain()
{
        printf("\ni m after termination of main and is
executing.........!!!\n");
}
