pvm_bufinfo Scilab // Group Scilab function pvm_bufinfo
NAME
pvm_bufinfo - Returns information about a message buffer.
CALLING SEQUENCE
[bytes, msgtag, tid, info] = pvm_bufinfo(bufid)
PARAMETERS
bufid : integer, specifying a particular message buffer
identifier.
bytes : integer, size of the message in bytes (non very useful inside
scilab).
msgtag : integer, label of the message. Useful when the message was
received with a wildcard msgtag.
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. If pvm_bufinfo is successful,
info will be 0. If some error occurs then info will be < 0.
EXAMPLE
[bytes, msgtag, tid, info] = pvm_info(bufid)
