# TMemoryStream.Write

Writes data to the stream's memory.

## Declaration

`public function TMemoryStream.Write(`
`const Buffer;`
`Count: LongInt`
`):LongInt; override;`

## Description

Write writes Count bytes from Buffer to the stream's memory, starting at the current position in the stream. If more memory is needed than currently allocated, more memory will be allocated. Any contents in the memory stream at the current position will be overwritten. The function returns the number of bytes actually written (which should under normal circumstances always equal Count).

This method overrides the abstract TStream.Write method.

## Errors

If no more memory could be allocated, then an exception will be raised.
