# VkSemaphoreSignalInfo(3) Manual Page

## Name

VkSemaphoreSignalInfo - Structure containing information about a semaphore signal operation

Loading... please wait.

## C Specification

The `VkSemaphoreSignalInfo` structure is defined as:

    typedef struct VkSemaphoreSignalInfo {
        VkStructureType    sType;
        const void*        pNext;
        VkSemaphore        semaphore;
        uint64_t           value;
    } VkSemaphoreSignalInfo;

or the equivalent

    typedef VkSemaphoreSignalInfo VkSemaphoreSignalInfoKHR;

## Members

- `sType` is the type of this structure.

- `pNext` is `NULL` or a pointer to an extension-specific structure.

- `semaphore` is the handle of the semaphore to signal.

- `value` is the value to signal.

## Description

Valid Usage

- `semaphore` must have been created with a VkSemaphoreType of `VK_SEMAPHORE_TYPE_TIMELINE`

- `value` must have a value greater than the current value of the semaphore

- `value` must be less than the value of any pending semaphore signal operations

- `value` must have a value which does not differ from the current value of the semaphore or the value of any outstanding semaphore wait or signal operation on `semaphore` by more than `maxTimelineSemaphoreValueDifference`

Valid Usage (Implicit)

- `sType` must be `VK_STRUCTURE_TYPE_SEMAPHORE_SIGNAL_INFO`

- `pNext` must be `NULL`

- `semaphore` must be a valid VkSemaphore handle
