pvm_bufinfo
Returns information about a message buffer.
Calling Sequence
[bytes, msgtag, tid, info] = pvm_bufinfo(bufid)
Arguments
- bufid
integer, specifying a particular message buffer identifier.
- bytes
integer, size of the message in bytes (not very useful inside scilab).
- msgtag
integer, label of the message. Useful when the message was received with a wildcard msgtag.
- tid
integer, task ID of the source of the message.
- info
integer, status code returned by the routine. Values less than zero indicate an error.
Description
pvm_bufinfo returns information about the requested message
buffer. Typically it is used to determine facts about the last
received message such as its size or source. pvm_bufinfo is
especially useful when an application is able to receive any incoming
message, and the action taken depends on the source tid and the msgtag
associated with the message that comes in first.
The returned value infowill be zero if
pvm_bufinfo is successful and will be
will be < 0 if some error occurs.
