DESCRIPTION¶
Thepmap_mincore
() function determines if the page at
the virtual address addr in the physical map
pmap is resident in physical memory. It is the
machine-dependent interface used by the mincore(2) system
call.
RETURN VALUES¶
If the page is resident in physical memory, a mask of flags is returned, whose meaning is documented in mincore(2); otherwise, 0 is returned.The pmap must exist and addr must be mapped into the pmap. If any error occurs, the machine-dependent implementation should return 0.
