vswscanf: wide-character formatted input of a
PROLOGThis manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.
vfwscanf, vswscanf, vwscanf - wide-character formatted input of a stdarg argument list
int vfwscanf(FILE *restrict stream, const wchar_t *restrict
int vswscanf(const wchar_t *restrict ws, const wchar_t *restrict format,
int vwscanf(const wchar_t *restrict format, va_list arg);
The vfwscanf(), vswscanf(), and vwscanf() functions shall be equivalent to the fwscanf(), swscanf(), and wscanf() 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.
Refer to fwscanf().
The following sections are informative.
Applications using these functions should call va_end( ap) afterwards to clean up.
