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; time_t ltime; char buf[26]; time( <ime ); _localtime( <ime, &time_of_day ); tprintf( 12, 1, "Date and time is: %s\n", _asctime( &time_of_day, buf ) ); }
