zx_interrupt_signal

NAME

interrupt_signal - signals a virtual interrupt on an interrupt object

SYNOPSIS

#include <zircon/syscalls.h>

zx_status_t zx_interrupt_signal(zx_handle_t handle, uint32_t slot, zx_time_t timestamp);

DESCRIPTION

interrupt_signal() is used to signal a virtual interrupt on an interrupt object. The slot parameter must have been bound to the interrupt object using interrupt_bind() with the ZX_INTERRUPT_VIRTUAL flag set, or be the special slot ZX_INTERRUPT_SLOT_USER.

interrupt_signal() will unblock a call to interrupt_wait() on the handle with the slot bit set in the interrupt_wait() out_slots parameter. After interrupt_wait() returns, the timestamp value can retrieved with interrupt_get_timestamp().

RETURN VALUE

interrupt_signal() returns ZX_OK on success. In the event of failure, a negative error value is returned.

ERRORS

ZX_ERR_BAD_HANDLE handle is not a valid handle.

ZX_ERR_BAD_STATE slot was not bound with the ZX_INTERRUPT_VIRTUAL flag set

ZX_ERR_INVALID_ARGS the slot parameter is invalid.
