# iniobuffer

Purpose
Retrieve amount of data in an IO buffer.
Synopsis
`function iniobuffer(stream:integer):integer`
Argument

stream | The stream to query:
F_INPUT | Input stream
F_OUTPUT | Output stream
F_ERROR | Error stream

Return value
Amount of data in bytes or -1 for an invalid stream specification
Further information
For all I/O operations Mosel uses buffers of 2048 bytes. This function makes it possible to know the amount of data currently held in the buffers associated to the current streams: for an input stream this corresponds to the data that has already been loaded from the driver but not yet consumed by the model and for an output stream this is the data that has been output but not yet sent to the driver.
