Not a lot of information to go on there but I guess you mean you want to do something like this:
Code:
typedef struct student_
{
int roll;
char name[30];
} student;
int displayStudent( FILE* uiTextArea, student *pStudent )
{
fprintf( uiTextArea, "Roll No #%i: %s", pStudent->roll, pStudent->name );
}
int main( void )
{
student defStudent = {0,"Default"};
return displayStudent( stdout, &defStudent );
}
If your talking about the keyword "this" then hate to break it to ya but it don't exist in normal C, OBJ-C might have it, I've never gone down that route before though so I wouldn't know
