vprintf, vfprintf, and vsprintf

#include <cstdarg>

#include <cstdio> int vprintf(char * format, va_list arg_ptr); int vfprintf(FILE * stream, const char *format, va_list arg_ptr); int vsprintf(char * buf, const char *format, va_list arg_ptr);

The functions vprintf( ), vfprintf( ), and vsprintf( ) are functionally equivalent to

printf( )

, fprintf( ), and sprintf( ), respectively, except that the argument list has been replaced by a pointer to a list of arguments. This pointer must be of type va_list, which is defined in the header <cstdarg> (or the C header file stdarg.h).

Related functions are va_arg( ), va_start( ), and va_end( ).
