clone_buffers()

int condy::BufferTable::clone_buffers ( BufferTable & src, unsigned int dst_off = 0, unsigned int src_off = 0, unsigned int nr = 0 )

inlinenoexcept

Clone buffers from another BufferTable into this one.

Parameters

src	The source BufferTable to clone from
dst_off	The starting offset in the destination buffer table
src_off	The starting offset in the source buffer table
nr	The number of buffers to clone

Returns

int Returns 0 on success or a negative error code on failure

Definition at line 143 of file ring_settings.hpp.

destroy()

int condy::BufferTable::destroy ( )

inlinenoexcept

Destroy the buffer table.

Returns

int Returns 0 on success or a negative error code on failure

Definition at line 117 of file ring_settings.hpp.

init() [1/2]

int condy::BufferTable::init ( const iovec * vecs, unsigned nr_vecs )

inline

Initialize the buffer table with the given array of iovec structures.

Parameters

vecs	Pointer to the array of iovec structures representing buffers
nr_vecs	Number of buffers in the array

Returns

Parameters

index_base	The starting index to update
vecs	Pointer to the array of iovec structures representing buffers
nr_vecs	Number of buffers to update

Returns

int Returns number of buffers updated on success or a negative error code on failure
