swscanf

Reads input from a wide-character string under control of the wide- character format string.

Format 

#include  <wchar.h>

int swscanf  (const wchar_t *s, const wchar_t
             *format, . . . );

Arguments

s
A pointer to a wide-character string from which the input is to be obtained.
format
A pointer to a wide-character string containing the format specifications. For more information about format and conversion specifications and their corresponding arguments, see Chapter 2.
. . .
Optional expressions whose results correspond to conversion specifications given in the format specification.

If no conversion specifications are given, you can omit the input pointers. Otherwise, the function calls must have exactly as many input pointers as there are conversion specifications, and the conversion specifications must match the types of the input pointers.

Conversion specifications are matched to input sources in left-to- right order. Excess input pointers, if any, are ignored.

Description

The swscanf function is equivalent to the fwscanf function, except that the first argument specifies a wide-character string rather than a stream. Reaching the end of the wide-character string is the same as encountering EOF for the fwscanf function.

See also fwscanf in this section.

Return Values
x  The number of input items assigned, sometimes fewer than provided for, or even 0 in the event of an early matching failure. 
EOF  Indicates and error. An input failure occurred before any conversion.
