VILLASnode/include/villas/nodes/amqp.h
Dennis Potter 72e627b327 Fixes #166, all node interfaces are modified
The functions now look like this

int node_read(struct node *n, struct sample *smps[], unsigned cnt, unsigned *release);
int node_write(struct node *n, struct sample *smps[], unsigned cnt, unsigned *release);

This commit enables nodes to control how many samples will
be released by the framework through *release
