LCB_KREQ_SIMPLE

#define LCB_KREQ_SIMPLE	(		req,
			k,
			nk )

Initialize a contiguous request backed by a buffer which should be copied.

Parameters

req	the key request to initialize
k	the key to copy
nk	the size of the key

Enumeration Type Documentation

lcb_KVBUFTYPE

enum lcb_KVBUFTYPE

Flags indicating the storage policy for a buffer.

Enumerator
LCB_KV_COPY	The buffer should be copied.
LCB_KV_CONTIG	The buffer is contiguous and should not be copied.
LCB_KV_IOV	The buffer is not contiguous and should not be copied.
LCB_KV_VBID	Indicates that the precomputed vBucket ID should be used.
LCB_KV_IOVCOPY	The buffers are not contiguous (multi-part buffers) but should be copied. This avoids having to make the buffers contiguous before passing it into the library (only to have the library copy it again)
