◆ grpc_byte_buffer_reader

Function Documentation

◆ grpc_byte_buffer_copy()

GRPCAPI grpc_byte_buffer* grpc_byte_buffer_copy ( grpc_byte_buffer bb)

Copies input byte buffer bb.

Increases the reference count of all the source slices. The user is responsible for calling grpc_byte_buffer_destroy over the returned copy.

◆ grpc_byte_buffer_destroy()

GRPCAPI void grpc_byte_buffer_destroy ( grpc_byte_buffer byte_buffer)

Destroys byte_buffer deallocating all its memory.

◆ grpc_byte_buffer_length()

GRPCAPI size_t grpc_byte_buffer_length ( grpc_byte_buffer bb)

Returns the size of the given byte buffer, in bytes.

◆ grpc_byte_buffer_reader_destroy()

GRPCAPI void grpc_byte_buffer_reader_destroy ( grpc_byte_buffer_reader reader)

Cleanup and destroy reader.

◆ grpc_byte_buffer_reader_init()

GRPCAPI int grpc_byte_buffer_reader_init ( grpc_byte_buffer_reader reader,
grpc_byte_buffer buffer 
)

Initialize reader to read over buffer.

Returns 1 upon success, 0 otherwise.

◆ grpc_byte_buffer_reader_next()

GRPCAPI int grpc_byte_buffer_reader_next ( grpc_byte_buffer_reader reader,
grpc_slice slice 
)

Updates slice with the next piece of data from from reader and returns.

  1. Returns 0 at the end of the stream. Caller is responsible for calling grpc_slice_unref on the result.

◆ grpc_byte_buffer_reader_peek()

GRPCAPI int grpc_byte_buffer_reader_peek ( grpc_byte_buffer_reader reader,
grpc_slice **  slice 
)

EXPERIMENTAL API - This function may be removed and changed, in the future.

Updates slice with the next piece of data from from reader and returns

  1. Returns 0 at the end of the stream. Caller is responsible for making sure the slice pointer remains valid when accessed.

NOTE: Do not use this function unless the caller can guarantee that the underlying grpc_byte_buffer outlasts the use of the slice. This is only safe when the underlying grpc_byte_buffer remains immutable while slice is being accessed.

◆ grpc_byte_buffer_reader_readall()

GRPCAPI grpc_slice grpc_byte_buffer_reader_readall ( grpc_byte_buffer_reader reader)

Merge all data from reader into single slice.

◆ grpc_raw_byte_buffer_create()

GRPCAPI grpc_byte_buffer* grpc_raw_byte_buffer_create ( grpc_slice slices,
size_t  nslices 
)

Returns a RAW byte buffer instance over the given slices (up to nslices).

Increases the reference count for all slices processed. The user is responsible for invoking grpc_byte_buffer_destroy on the returned instance.

◆ grpc_raw_byte_buffer_from_reader()

GRPCAPI grpc_byte_buffer* grpc_raw_byte_buffer_from_reader ( grpc_byte_buffer_reader reader)

Returns a RAW byte buffer instance from the output of reader.

◆ grpc_raw_compressed_byte_buffer_create()

GRPCAPI grpc_byte_buffer* grpc_raw_compressed_byte_buffer_create ( grpc_slice slices,
size_t  nslices,
grpc_compression_algorithm  compression 
)

Returns a compressed RAW byte buffer instance over the given slices (up to nslices).

The compression argument defines the compression algorithm used to generate the data in slices.

Increases the reference count for all slices processed. The user is responsible for invoking grpc_byte_buffer_destroy on the returned instance.
