#include <sys/vminfo.h> int swapqry (PathName, Buffer) char PathName; struct pginfo *Buffer;
The swapqry subroutine returns information to a user-designated buffer about active paging and swap devices.
PathName | Specifies the full path name of the block device. |
Buffer | Points to the buffer into which the status is stored. |
The swapqry subroutine returns 0 if the PathName value is an active paging device. If the Buffer value is not null, it also returns status information.
If an error occurs, the subroutine returns -1 and the errno global variable is set to indicate the error, as follows:
This subroutine is part of Base Operating System (BOS) Runtime.
