TStream.WriteBuffer

TStream


Writes Count bytes from Buffer onto the stream and advances the current position of the stream by Count bytes.

 

procedure WriteBuffer(const Buffer; Count: Longint);

 

Description

Use WriteBuffer to save data to a stream. WriteBuffer and ReadBuffer are used in cases where the number of bytes is known and required, for example when reading in structures. Use WriteBuffer for standard file I/O streaming.

 

WriteBuffer is used internally for writing to a stream and copying from a stream. It is used by other objects, such as strings and lists, for writing strings to a buffer.

 

WriteBuffer calls Write to handle the actual writing. If the stream fails to write all the requested bytes, an EWriteError exception is raised.
