/* C objects to be exported from one extension module to another.
|
|
|
|
C objects are used for communication between extension modules.
|
|
They provide a way for an extension module to export a C interface
|
|
to other extension modules, so that extension modules can use the
|
|
Python import mechanism to link to one another.
