_scprintf, _scwprintf
Return the number of characters in the formatted string.
int _scprintf( const char *format [, argument] ... ); int _scwprintf( const wchar_t *format [, argument] ... );
Parameters
- format
- Format-control string.
- argument
- Optional arguments.
For more information, see Format Specifications.
Return Value
Returns the number of characters that would be generated if the string were to be printed or sent to a file or buffer using the specified formatting codes. The value returned does not include the terminating null character. _scwprintf performs the same function for wide characters.
Remarks
Each argument (if any) is converted according to the corresponding format specification in format. The format consists of ordinary characters and has the same form and function as the format argument for printf.
Security Note Ensure that format is not a user-defined string.
