Reads in formatted data from a wide-character string

 #include <wchar.h> int swscanf ( 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
