vscanf#

Synopsis#

#include <stdarg.h> #include <stdio.h>

int vfscanf(FILE *restrict stream, const char *restrict format, va_list arg);

int vscanf(const char *restrict format, va_list arg);

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

Status#

Partially implemented

Conformance#

IEEE Std 1003.1, 2017

Description#

The vscanf(), vfscanf(), and vsscanf() functions shall be equivalent to the scanf(), fscanf(), and sscanf() functions, respectively, except that instead of being called with a variable number of arguments, they are called with an argument list as defined in the <stdarg.h> header. 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.

Return value#

Refer to fscanf.

Errors#

Refer to fscanf.

Tests#

Untested
