MINCORE(2)		    BSD	System Calls Manual		    MINCORE(2)

NAME
     mincore --	get advice about use of	memory

LIBRARY
     Standard C	Library	(libc, -lc)

SYNOPSIS
     #include <sys/mman.h>

     int
     mincore(const void	*addr, size_t len, char	*vec);

DESCRIPTION
     The mincore() system call allows a	process	to obtain information about
     whether pages are core resident.  Here the	current	core residency of the
     pages is returned in the character	array vec, with	a value	of 1 meaning
     that the page is in-core.

RETURN VALUES
     The mincore() function returns the	value 0	if successful; otherwise the
     value -1 is returned and the global variable errno	is set to indicate the
     error.

ERRORS
     [EINVAL]		The virtual address range specified by the addr	and
			len arguments is not valid.

     [EFAULT]		The vec	argument points	to an illegal address.

BUGS
     This man page is incorrect.  The vector description is wrong.
