     mincore - determine residency of memory pages


SYNOPSIS

     #include <sys/types.h>
     #include <sys/mman.h>

     int
     mincore(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.
