Hey Everyone,

minherit
MINHERIT(2) BSD System Calls Manual MINHERIT(2)NAME
minherit -- control the inheritance of pages
SYNOPSIS
#include <sys/types.h>
#include <sys/mman.h>
int
minherit(caddr_t addr, size_t len, int inherit);
DESCRIPTION
The minherit() system call changes the specified pages to have the inheritance characteristic inherit, which can be set to VM_INHERIT_NONE,
VM_INHERIT_COPY, or VM_INHERIT_SHARE. Not all implementations will guarantee that the inheritance characteristic can be set on a page basis;
the granularity of changes may be as large as an entire region.
RETURN VALUES
The minherit() function returns the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set to indi-
cate the error.
ERRORS
The minherit() system call will fail if:
[EINVAL] The virtual address range specified by the addr and len arguments is not valid.
[EACCES] The flags specified by the inherit argument were not valid for the pages specified by the addr and len arguments.
SEE ALSO madvise(2), mincore(2), mprotect(2), msync(2), munmap(2)HISTORY
The minherit() function first appeared in OpenBSD.
