|
* This file contains declarations of things that are visible everywhere
|
|
* in openGauss *and* are visible to clients of frontend interface libraries.
|
|
* For example, the Oid type is part of the API of libpq and other libraries.
|
|
*
|
|
* Declarations which are specific to a particular interface should
|
|
* go in the header file for that interface (such as libpq-fe.h). This
|
|
* file is only for fundamental openGauss declarations.
|
|
*
|
|
* User-written C functions don't count as "external to openGauss."
|
|
* Those function much as local modifications to the backend itself, and
|
|
* use header files that are otherwise internal to openGauss to interface
|
|
* with the backend.
