Struct CFData

pub struct CFData(/* private fields */);

This provides support for data objects, object-oriented wrappers for byte buffer

Implementations

impl CFData

pub unsafe fn create( allocator: CFAllocatorRef, bytes: *const UInt8, length: CFIndex, ) -> CFData

Creates an immutable CFData object using data copied from a specified byte buffer.

Safety

This function dereferences a raw pointer

pub unsafe fn create_copy(allocator: CFAllocatorRef, data: CFDataRef) -> CFData

Creates an immutable copy of a CFData object.

Safety

This function dereferences a raw pointer

pub unsafe fn create_with_bytes_no_copy( allocator: CFAllocatorRef, bytes: *const UInt8, length: CFIndex, bytes_deallocator: CFAllocatorRef, ) -> CFData

Creates an immutable CFData object from an external (client-owned) byte buffer.

Safety

This function dereferences a raw pointer

pub unsafe fn get_byte_ptr(data: CFDataRef) -> *const UInt8

Returns a read-only pointer to the bytes of a CFData object.

Safety

This function dereferences a raw pointer

pub unsafe fn get_bytes(data: CFDataRef, range: CFRange, buffer: *mut u8)

Copies the byte contents of a CFData object to an external buffer.

Safety

This function dereferences a raw pointer

pub unsafe fn get_length(data: CFDataRef) -> CFIndex

Returns the number of bytes contained by a CFData object.

Safety

This function dereferences a raw pointer

pub unsafe fn find( data: CFDataRef, data_to_find: CFDataRef, search_range: CFRange, compare_options: CFDataSearchFlags, ) -> CFRange

Finds and returns the range within a data object of the first occurrence of the given data, within a given range, subject to any given options.

Safety

This function dereferences a raw pointer

pub fn get_type_id() -> CFTypeID

Returns the type identifier for the CFData opaque type.
