This extension is a generic extension API to DLLs. This was originally
|
|
written to allow access to the Win32 API from PHP, although you can also
|
|
access other functions exported via other DLLs.

Currently supported types are generic PHP types (strings, booleans, floats,

integers and nulls) and types you define with <function>w32api_deftype</function>.
