vsprintf

Equivalent to sprintf, with the variable argument list replaced by arg, which has been

initialized by the

va_start macro (and possibly subsequent va_arg calls). The

vsprintf function does not invoke the va_end function.

Synopsis

#include <stdarg.h>

#include <stdio.h>

int vsprintf(char *s, const char *format, va_list arg);

Returns

The number of characters written in the array, not counting the terminating null character.

Example

va_list va;

char buf[80];

/*initialize the variable argument va here*/

vsprint(buf, "%d %d %d",va);
