FS_SETSWAP

Purpose

Perform whatever actions are necessary to support the swapper.

Calling Sequence

int far pascal FS_SETSWAP(psffsi, psffsd)
 
struct sffsi far * psffsi;
struct sffsd far * psffsd;

Where

psffsi is a pointer to the file-system-independent portion of an open file instance of the swapper file.

psffsd is a pointer to the file-system-dependent portion of an open file instance.

Remarks

Swapping does not begin until this call returns successfully. This call is made during system initialization.

The FSD makes all segments that are relevant to swap-file I/O non-swappable (see FSH_FORCENOSWAP). This includes any data and code segments accessed during a read or write.

Any FSD that manages writeable media may be the swapper file system.

FS_SETSWAP may be called more than once for the same or different volumes or FSDs.
