= Description
A Ruby library that adds some core FFI and String methods to supplement
development of Ruby libraries on Windows.
= Installation
gem install ffi-win32-extensions
= Details
The following FFI::MemoryPointer methods have been added:
* read_array_of_string - For reading char** types.
* read_wide_string - Similar to read_string but for wide char* types.
The following FFI module functions have been added:
* windows_error_message - A Windows specific error string using FormatMessage.
* raise_windows_error - Raises a windows specific error using windows_error_message.
The following String instance methods have been added:
* wincode - Converts a string to UTF-16LE for use in wide char functions.
* wstrip - Like String#strip, but for wide strings.
* read_wide_string - Reads a Ruby string up to the first double null.
Example:
require 'ffi/win32/extensions'
str = old_string.wincode
rv = SomeWideFunctionW(str)
unless rv == 0
FFI.raise_windows_error('SomeWindowsFunction', rv)
