MINHERIT(2) BSD Programmer's Manual MINHERIT(2)
minherit - control the inheritance of pages
#include <sys/types.h> #include <sys/mman.h> int minherit(void *addr, size_t len, int inherit);
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.
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.
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.
