Win32::API::Type - C type support package for Win32::API
use Win32::API; Win32::API::Type->typedef( 'my_number', 'LONG' );
This module is a support package for Win32::API that implements C types for the import with prototype functionality.
See Win32::API for more info about its usage.
This module is automatically imported by Win32::API, so you don't need to 'use' it explicitly. These are the methods of this package:
typedef NAME, TYPE
This method defines a new type named
NAME. This actually just creates an alias for the already-defined type
TYPE, which you can use as a parameter in a Win32::API call.
TYPEcontains a Win32::API::Struct type declared with "typedef" in Win32::API::Struct with " *" postfixed to
NAMEwill be a alias for the pointer version of the struct type. Creating an alias for a struct type is not supported, you have to call "typedef" in Win32::API::Struct again. Passing a struct type as
TYPEwithout the " *" postfix is not supported.
Warns and returns undef if
TYPEis unknown, else returns true.
This returns the size, in bytes, of
TYPE. Acts just like the C function of the same name.
Returns true if
TYPEis known by Win32::API::Type, false otherwise.
This module recognizes many commonly used types defined in the Win32 Platform SDK header files, but not all. Types less than 13 years old are very unlikely to be the in built type database.
Please see the source for this module, in the
__DATA__ section, for the full list of builtin supported types.
NOTES ON SELECT TYPES
Due to poor design, currently LPVOID is a char *, a string, not a number. It should really be a number. It is suggested to replace LPVOID in your C prototypes passed to Win32::API with UINT_PTR which is a pointer sized number.
- SOMETYPE **
Currently ** types do not parse.
- void **
Replace void ** in your C prototype that you pass to Win32::API::More with LPHANDLE.
- unsigned char
- signed char
These 2 types by name force numeric handling.
UCHARis not a
unsigned charfor numeric handling purposes.
