Undocumented in source.

Members

Enums

AHardwareBuffer_Format enum AHardwareBuffer_Format: Buffer pixel formats.
AHardwareBuffer_UsageFlags enum AHardwareBuffer_UsageFlags: Buffer usage flags, specifying how the buffer will be accessed.

Functions

AHardwareBuffer_acquire void AHardwareBuffer_acquire(AHardwareBuffer* buffer): Acquire a reference on the given AHardwareBuffer object.
AHardwareBuffer_allocate
int AHardwareBuffer_allocate(AHardwareBuffer_Desc* desc, AHardwareBuffer** outBuffer): Allocates a buffer that matches the passed AHardwareBuffer_Desc.
AHardwareBuffer_describe void AHardwareBuffer_describe(AHardwareBuffer* buffer, AHardwareBuffer_Desc* outDesc): Return a description of the AHardwareBuffer in the passed AHardwareBuffer_Desc struct.
AHardwareBuffer_isSupported int AHardwareBuffer_isSupported(AHardwareBuffer_Desc* desc): Test whether the given format and usage flag combination is allocatable.
AHardwareBuffer_lock
int AHardwareBuffer_lock(AHardwareBuffer* buffer, uint64_t usage, int32_t fence, ARect* rect, void** outVirtualAddress): Lock the AHardwareBuffer for direct CPU access.
AHardwareBuffer_lockAndGetInfo
int AHardwareBuffer_lockAndGetInfo(AHardwareBuffer* buffer, uint64_t usage, int32_t fence, ARect* rect, void** outVirtualAddress, int32_t* outBytesPerPixel, int32_t* outBytesPerStride): Lock an AHardwareBuffer for direct CPU access.
AHardwareBuffer_lockPlanes int AHardwareBuffer_lockPlanes(AHardwareBuffer* buffer, uint64_t usage, int32_t fence, ARect* rect, AHardwareBuffer_Planes* outPlanes): Lock a potentially multi-planar AHardwareBuffer for direct CPU access.
AHardwareBuffer_recvHandleFromUnixSocket
int AHardwareBuffer_recvHandleFromUnixSocket(int socketFd, AHardwareBuffer** outBuffer): Receive an AHardwareBuffer from an AF_UNIX socket.
AHardwareBuffer_release void AHardwareBuffer_release(AHardwareBuffer* buffer): Remove a reference that was previously acquired with AHardwareBuffer_acquire() or AHardwareBuffer_allocate().
AHardwareBuffer_sendHandleToUnixSocket int AHardwareBuffer_sendHandleToUnixSocket(AHardwareBuffer* buffer, int socketFd): Send the AHardwareBuffer to an AF_UNIX socket.
AHardwareBuffer_unlock int AHardwareBuffer_unlock(AHardwareBuffer* buffer, int32_t* fence): Unlock the AHardwareBuffer from direct CPU access.

Structs

AHardwareBuffer struct AHardwareBuffer: Opaque handle for a native hardware buffer.
AHardwareBuffer_Desc struct AHardwareBuffer_Desc: Buffer description. Used for allocating new buffers and querying parameters of existing ones.
AHardwareBuffer_Plane struct AHardwareBuffer_Plane: Holds data for a single image plane.
AHardwareBuffer_Planes struct AHardwareBuffer_Planes: Holds all image planes that contain the pixel data.
