C in a Nutshell

Name

swscanf

Synopsis

Reads in formatted data from a wide-character string

#include <wchar.h>
intswscanf( const wchar_t * restrict wcs,
             const wchar_t * restrict format, ... );

The swscanf() function is similar to wscanf(), except that it reads its input from the wide-character string addressed by the first argument, wcs, rather than from stdin. If swscanf() reads to the end of the string, it returns the value EOF.

Example

double price = 0.0;
wchar_t wstr[ ] = L"Current price: $199.90";swscanf( wstr, L"%*[^$]$%lf", &price);      // Read price from string.
price *= 0.8;                               // Apply 20% discount.
printf( "New price: $%.2lf\n", price);

This code produces the following output:

New price: $159.92
