* aio_subsys.h

|
* Interaction with AIO as a subsystem, rather than actually issuing AIO
|
|
*
|
|
* This header is for AIO related functionality that's being called by files
|
|
* that don't perform AIO, but interact with the AIO subsystem in some
|
|
* form. E.g. postmaster.c and shared memory initialization need to initialize
|
|
* AIO but don't perform AIO.
