NAME
vfprintf, vprintf, vsnprintf, vsprintf - format output of a stdarg argument list SYNOPSIS
#include <stdarg.h> #include <stdio.h> int vfprintf(FILE *restrict stream, const char *restrict format, va_list ap); int vprintf(const char *restrict format, va_list ap); int vsnprintf(char *restrict s, size_t n, const char *restrict format, va_list ap); int vsprintf(char *restrict s, const char *restrict format, va_list ap); DESCRIPTION
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 unspeci- fied. RETURN VALUE
Refer to fprintf() . ERRORS
Refer to fprintf() . The following sections are informative. EXAMPLES
None. APPLICATION USAGE
Applications using these functions should call va_end(ap) afterwards to clean up. RATIONALE
None. FUTURE DIRECTIONS
None. SEE ALSO
