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 inher-
itance characteristic inherit, which can be set to VM_INHERIT_NONE,
VM_INHERIT_COPY, or VM_INHERIT_SHARE. Not all implementations will guar-
antee 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 indicate 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.
