MirOS Manual: minherit(2)

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

NAME

     minherit - control the inheritance of pages

SYNOPSIS

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

     int
     minherit(void *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 MAP_INHERIT_NONE,
     MAP_INHERIT_COPY, or MAP_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 indicate the
     error.

ERRORS

     The minherit() system call will fail if:

     [EINVAL]      The virtual address range specified by the addr and len ar-
                   guments is not valid.

     [EACCES]      The flags specified by the inherit argument were not valid
                   for the pages specified by the addr and len arguments.
