PFStream

A stream is sequence of bytes. Small streams (<256K) reside in memory, and large streams are flushed to temporary files. These files are created in a folder specified during initializing the library. If the library is not initialized during creating a stream, the files are created in a temporary folder.

tStreamPos seek(tStreamPos offset, int origin);
Parameters:

  • offset – Offset from origin

  • origin – FILE_BEGIN, FILE_CURRENT or FILE_END

Description:

Moves the stream pointer to a specified location.

tStreamSize read(void *buffer, tStreamSize size);
Parameters:

  • buffer – Pointer to data buffer

  • size – Size of buffer

Description:

Reads data from a stream and returns the number of bytes actually read.

tStreamSize write(const void *buffer, tStreamSize size);
Parameters:

  • buffer – Pointer to data buffer

  • size – Size of buffer

Description:

Writes data to a stream and returns the number of bytes actually written.

tStreamPos size();
Description:

Returns number of bytes in stream.

tStreamPos copyTo(PFStream *pStream);
Description:
