|
pure virtual |
Read some bytes from this stream and stores them into a buffer.
- Parameters
-
count | A pointer to a value containing the number of bytes should be read. After this call it contains the number of read bytes. |
buffer | A memory buffer |
Implemented in CPGFFileStream, and CPGFMemoryStream.

) |
| |
|
pure virtual |
Set stream position either absolute or relative.
- Parameters
-
posMode | A position mode (FSFromStart, FSFromCurrent, FSFromEnd) |
posOff | A new stream position (absolute positioning) or a position offset (relative positioning) |
Implemented in CPGFFileStream, and CPGFMemoryStream.
◆ Write()
virtual void CPGFStream::Write |
( |
int * |
count, |
|
|
void * |
buffer |
|
) |
| |
|
pure virtual |
Write some bytes out of a buffer into this stream.
- Parameters
-
count | A pointer to a value containing the number of bytes should be written. After this call it contains the number of written bytes. |
buffer | A memory buffer |
Implemented in CPGFFileStream, and CPGFMemoryStream.
