"""The CLibrary class is intended to automate much of the work in using ctypes by integrating
|
||
|
|
header file definitions from CParser. Ths class serves as a proxy to a ctypes, adding
|
||
|
|
a few features:
|
||
|
|
- allows easy access to values defined via CParser
|
||
|
|
- automatic type conversions for function calls using CParser function signatures
|
||
|
|
- creates ctype classes based on type definitions from CParser
|
||
|
|
|
||
|
|
Initialize using a ctypes shared object and a CParser:
|
||
|
|
headers = CParser.winDefs()
|
||
|
|
lib = CLibrary(windll.User32, headers)
|
||
|
|
|
||
|
|
There are 3 ways to access library elements:
|
||
|
|
lib(type, name) - type can be one of 'values', 'functions', 'types', 'structs', 'unions', or 'enums'.
|
||
|
|
Returns an object matching name. For values, the value from the headers is
|
||
|
|
returned. For functions, a callable object is returned that handles automatic
|
||
|
|
type conversion for arguments and return values. for structs, types, and enums,
|
||
|
|
a ctypes class is returned matching the type specified.
|
||
|
|
lib.name - searches in order through values, functions, types, structs, unions, and enums from
|
||
|
|
header definitions and returns an object for the first match found. The object
|
||
|
|
returned is the same as returned by lib(type, name). This is the preferred way to access
|
||
|
|
elements from CLibrary, but may not work in some situations (for example, if
|
||
|
|
a struct and variable share the same name).
|
||
|
|
lib[type] - Accesses the header definitions directly, returns definition dictionaries
|
||
|
|
based on the type requested. This is equivalent to headers.defs[type].

- Original ctype objects can be accessed via result.rval or result.args

- The return value: ()

- The nth argument passed: [n]

- The argument by name: ['name']

|
- All values that were auto-generated: .auto()
