zx_pager_create

SUMMARY

Create a new pager object.

DECLARATION

#include <zircon/syscalls.h>

zx_status_t zx_pager_create(uint32_t options, zx_handle_t* out);

DESCRIPTION

zx_pager_create() creates a new pager object.

When a pager object is destroyed, any accesses to its vmos that would have required communicating with the pager will fail as if zx_pager_detach_vmo() had been called. Furthermore, the kernel will make an effort to ensure that the faults happen as quickly as possible (e.g. by evicting present pages), but the precise behavior is implementation dependent.

RIGHTS

Caller job policy must allow ZX_POL_NEW_PAGER.

RETURN VALUE

zx_pager_create() returns ZX_OK on success, or one of the following error codes on failure.

ERRORS

ZX_ERR_INVALID_ARGS out is an invalid pointer or NULL or options is any value other than 0.

ZX_ERR_NO_MEMORY Failure due to lack of memory.
