| Name | rd/wr | Description |
| port | read | Port to listen to (on caller's node). |
| source | read | Source node to listen to. |
| tag | read | tag to use. |
| request | write | Request descriptor to hold the status. |
| buffer | write | Receive buffer. |
This function performs a blocking receive on a given port port, from a given source node source (or A0AnySource if any node will do), with a given tag tag. It blocks the calling thread to receive data into the buffer buffer.
The full contents of a buffer is replaced every time a receive is performed. There is no need to call a0ClearBuffer() prior to receive it.
On return of this function, the variable pointed by request contains an opaque request that can be used later to check the completion status of the receive operation.
