The MSpan method

This method searches for the first occurrence in the multibyte character string s1 of any character from the multibyte character string s2.

char *MSpan(const char *s1, const char *s2,
          int nbytes1 = ITLocale::ScanToNul, 
          int nbytes2 = ITLocale::ScanToNul) const

The nbytes1 and nbytes2 parameters specify the length of the s1 and s2 strings. You can provide an integer to specify the number of bytes in the corresponding string. Or you can use the constant ITLocale::ScanToNul (the default) to specify that the corresponding string is null-terminated.

This method returns a pointer to the first occurrence in s1 of any character from s2. If no character from s2 is found in s1 the method returns NULL and ITLocale::GetError() returns 0.

If an error occurs, the method returns NULL and ITLocale::GetError() returns a specific error message.
