32 """Function binding conditions can be specified manually by supplying a versions
33 array instead of the names array. Each version has the following keys:
34 name: Mandatory. Name of the function. Multiple versions can have the same
35 name but different conditions.
36 extensions: Extra Extensions for which the function is bound. Only needed
37 in some cases where the extension cannot be parsed from the
38 headers.
39 is_optional: True if the GetProcAddress can return NULL for the
40 function. This may happen for example when functions
41 are added to a new version of an extension, but the
42 extension string is not modified.
43 By default, the function gets its name from the first name in its names or
44 versions array. This can be overridden by supplying a 'known_as' key.
