Declaration

pascal

function Read(var Buffer; Count: LongInt): LongInt; override

Arguments

`Buffer`	Memory buffer for the read data.
`Count`	Number of bytes to read.

Description

Read checks first whether the type of the stream allows reading (type is iosInput). If not, it raises a EIOStreamError exception. If the stream can be read, it calls the inherited Read to actually read the data.

Errors

An EIOStreamError exception is raised if the stream does not allow reading.
