     mincore - determine residency of memory pages

SYNOPSIS
     #include <sys/types.h>

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
     Upon successful completion, a value of 0 is returned.  Otherwise, a value
     of -1 is returned and errno is set to indicate the error.
