Function Documentation

◆ grpc_slice_buffer_add()

GPRAPI void grpc_slice_buffer_add ( grpc_slice_buffer sb,
grpc_slice  slice 
)

Add an element to a slice buffer - takes ownership of the slice.

This function is allowed to concatenate the passed in slice to the end of some other slice if desired by the slice buffer.

◆ grpc_slice_buffer_add_indexed()

GPRAPI size_t grpc_slice_buffer_add_indexed ( grpc_slice_buffer sb,
grpc_slice  slice 
)

add an element to a slice buffer - takes ownership of the slice and returns the index of the slice.

Guarantees that the slice will not be concatenated at the end of another slice (i.e. the data for this slice will begin at the first byte of the slice at the returned index in sb->slices) The implementation MAY decide to concatenate data at the end of a small slice added in this fashion.

◆ grpc_slice_buffer_addn()

GPRAPI void grpc_slice_buffer_addn ( grpc_slice_buffer sb,
grpc_slice slices,
size_t  n

initialize a slice buffer

◆ grpc_slice_buffer_move_first()

GPRAPI void grpc_slice_buffer_move_first ( grpc_slice_buffer src,

◆ grpc_slice_buffer_move_first_into_buffer()

GPRAPI void grpc_slice_buffer_move_first_into_buffer ( grpc_slice_buffer src,

◆ grpc_slice_buffer_move_first_no_ref()
