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

NAME
     mincore -- determine residency of memory pages

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

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

SEE ALSO

HISTORY
     The mincore() function first appeared in 4.4BSD.
