Description

Methods responsible for writing up to Count bytes from Buffer to the stream.

WriteData is used in cases, where the number of bytes to write to the stream is not necessarily fixed.

WriteData works using the following algorithms:

• When WriteData does not have the Count parameter, then WriteData tries to write the SizeOf(Buffer) number of bytes. WriteData advances the current position in the stream by the number of bytes transferred. WriteData returns the number of bytes written.
• When WriteData has the Count parameter, then:
  • If Count > SizeOf(Buffer), then WriteData tries to write the SizeOf(Buffer) number of bytes. WriteData advances the current position in the stream by the Count number of bytes.
  • If Count <= SizeOf(Buffer), then WriteData tries to write up to the Count number of bytes to the stream and then advances the current position in the stream by the number of bytes transferred. WriteData returns the number of bytes written, which may be less than Count.

WriteData methods call Write to do their actual writing.
