finish getting items from a variable argument list
#include <stdarg.h> void va_end( va_list param );
va_end() is a macro used to complete the acquisition of arguments from a list of variable arguments. It must be used with the associated macros va_start() and va_arg(). See the description for va_arg() for complete documentation on these macros.
#include <stdio.h>
#include <stdarg.h>
#include <time.h>
#define ESCAPE 27
void tprintf( int row, int col, char *fmt, ... )
{
va_list ap;
char *p1, *p2;
va_start( ap, fmt );
p1 = va_arg( ap, char * );
p2 = va_arg( ap, char * );
printf( "%c[%2.2d;%2.2dH", ESCAPE, row, col );
printf( fmt, p1, p2 );
va_end( ap );
}
void main()
{
struct tm time_of_day;

tprintf( 12, 1, "Date and time is: %s\n",
_asctime( &time_of_day, buf ) );
