int vfprintf(FILE *restrict
stream, const char
*restrict format,
va_list
ap );
int vprintf(const char *restrict
format, va_list

int vsnprintf(char *restrict

int vsprintf(char *restrict
s, const char
*restrict format, va_list
ap );
The
vprintf(),
vfprintf(),
vsnprintf(), and
vsprintf() functions shall be equivalent to
printf(),
fprintf(),
snprintf(), and
sprintf() respectively, except
that instead of being called with a variable number of arguments, they are
called with an argument list as defined by
<stdarg.h>.
These functions shall not invoke the
va_end macro. As these functions
invoke the
va_arg macro, the value of
ap after the return is
unspecified.
Refer to
fprintf() .
Refer to
fprintf() .
The following sections are informative.
None.
Applications using these functions should call
va_end(
ap)
afterwards to clean up.
None.
None.
