MINCORE(2) BSD System Calls Manual MINCORE(2)NAMEmincore — determine residency of memory pages
mincore(caddr_t addr, size_t len, char *vec);
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.
Upon successful completion, a value of 0 is returned. Otherwise, a value
of -1 is returned and errno is set to indicate the error.
