Function SecTransformRegister 

pub unsafe extern "C-unwind" fn SecTransformRegister(
    unique_name: &CFString,
    create_transform_function: SecTransformCreateFP,
    error: *mut *mut CFError,
) -> bool

👎Deprecated: SecTransform is no longer supported

Available on crate features SecCustomTransform and SecTransform and block2 only.

Register a new custom transform so that it may be used to process data

Parameter uniqueName: A unique name for this custom transform. It is recommended that a reverse DNS name be used for the name of your custom transform

Parameter createTransformFunction: A SecTransformCreateFP function pointer. The function must return a SecTransformInstanceBlock block that block_copy has been called on before returning the block. Failure to call block_copy will cause undefined behavior.

Parameter error: This pointer is set if an error occurred. This value may be NULL if you do not want an error returned.

Returns: True if the custom transform was registered false otherwise

Safety

• create_transform_function must be implemented correctly.
• error must be a valid pointer or null.
