SYNOPSIS

In sys/param.h In vm/vm.h In vm/vm_map.h Ft int Fo vm_map_clean Fa vm_map_t map vm_offset_t start vm_offset_t end boolean_t syncio Fa boolean_t invalidate Fc

DESCRIPTION

The Fn vm_map_clean function forces any dirty cached pages in the range Fa start to Fa end within the Fa map to be pushed to their underlying pager.

If Fa syncio is TRUE, dirty pages are written synchronously.

If Fa invalidate is TRUE, any cached pages are also freed.

The range provided must be contiguous, it MUST NOT contain holes. The range provided MUST NOT contain any sub-map entries.

IMPLEMENTATION NOTES

This routine holds the Giant lock to prevent multiple entry.

RETURN VALUES

The Fn vm_map_clean function returns KERN_SUCCESS if successful.

Otherwise, KERN_INVALID_ADDRESS will be returned if the function encountered a sub-map entry; KERN_INVALID_ARGUMENT will be returned if the function encountered a hole in the region provided, or if an entry could not be found for the given start address.
