MINCORE(2)                 BSD Programmer's Manual                  MINCORE(2)

NAME

     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.

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.

     The mincore() function first appeared in 4.4BSD.
