The actual number of characters copied.

If you pass a dst buffer that is a null reference (Nothing in Visual Basic), GetChars returns the length of the field in characters.

The characters at position srcOffset through srcOffset +count -1 of the value are copied into positions dstOffset through dstOffset +count -1, respectively, of the destination array. If the end of the value is encountered before count characters are copied, the remainder of the destination array is left unchanged.

If any of the following is true, a ULException with code ULSQLCode.SQLE_INVALID_PARAMETER is thrown and the destination is not modified:

For other errors, a ULException with the appropriate error code is thrown.

• GetFieldType method
• ULException class
