Ixp_pdata
#include <ixp.h> void ixp_pdata(IxpMsg *msg, char **data, uint len);
Packs or unpacks a raw character buffer of size len.
If msg->mode is MsgPack, buffer pointed to by data is packed into the buffer at msg->pos. If msg->mode is MsgUnpack, the address pointed to by s is loaded with a malloc(3) allocated buffer with the contents of the buffer at msg->pos. In either case, msg->pos is advanced by the number of bytes read or written. If the action would advance msg->pos beyond msg->end, msg->pos is still advanced but no other action is taken.
