## Topics

### Errors

[`var kCMBlockBufferBadCustomBlockSourceErr: OSStatus`](/documentation/CoreMedia/kCMBlockBufferBadCustomBlockSourceErr)

An error code that indicates the custom block source is invalid.

[`var kCMBlockBufferBadLengthParameterErr: OSStatus`](/documentation/CoreMedia/kCMBlockBufferBadLengthParameterErr)

An error code that indicates the block length is zero or doesn’t equal the size of the memory block.

[`var kCMBlockBufferBadOffsetParameterErr: OSStatus`](/documentation/CoreMedia/kCMBlockBufferBadOffsetParameterErr)

An error code that indicates the offset doesn’t point to the location of data in the memory block.

[`var kCMBlockBufferBadPointerParameterErr: OSStatus`](/documentation/CoreMedia/kCMBlockBufferBadPointerParameterErr)

An error code that indicates the block buffer reference is invalid.

[`var kCMBlockBufferBlockAllocationFailedErr: OSStatus`](/documentation/CoreMedia/kCMBlockBufferBlockAllocationFailedErr)

An error code that indicates the block allocator failed to allocate a memory block.

[`var kCMBlockBufferEmptyBBufErr: OSStatus`](/documentation/CoreMedia/kCMBlockBufferEmptyBBufErr)

An error code that indicates the block buffer is empty.

[`var kCMBlockBufferInsufficientSpaceErr: OSStatus`](/documentation/CoreMedia/kCMBlockBufferInsufficientSpaceErr)

An error code that indicates the system failed to create a new buffer because of insufficient space at the buffer out location.

[`var kCMBlockBufferStructureAllocationFailedErr: OSStatus`](/documentation/CoreMedia/kCMBlockBufferStructureAllocationFailedErr)

An error code that indicates the structure allocator failed to allocate a block buffer.

[`var kCMBlockBufferUnallocatedBlockErr: OSStatus`](/documentation/CoreMedia/kCMBlockBufferUnallocatedBlockErr)

An error code that indicates the system encountered an unallocated memory block.

[`var kCMBlockBufferNoErr: OSStatus`](/documentation/CoreMedia/kCMBlockBufferNoErr)

A code that indicates the system successfully created a block buffer with no errors.
