## ◆ close()

virtual bool PtexReader::DefaultInputHandler::close | ( | Handle | handle | ) |
| inline virtual

Close a file.

Returns false if an error occurs, and the error string is available via lastError().

Implements PtexInputHandler.

Definition at line 629 of file PtexReader.h.

References buffer, and PtexReader::ok().

## ◆ lastError()

virtual const char * PtexReader::DefaultInputHandler::lastError | ( |  | ) |
| inline virtual

Return the last error message encountered.

Implements PtexInputHandler.

Definition at line 634 of file PtexReader.h.

## ◆ open()

virtual Handle PtexReader::DefaultInputHandler::open | ( | const char * | path | ) |
| inline virtual

Open a file in read mode.

Returns null if there was an error. If an error occurs, the error string is available via lastError().

Implements PtexInputHandler.

Definition at line 616 of file PtexReader.h.

## ◆ read()

virtual size_t PtexReader::DefaultInputHandler::read | ( | void * | buffer,
|  | size_t | size,
|  | Handle | handle
| ) |  |
| inline virtual

Read a number of bytes from the file.

Returns the number of bytes successfully read. If less than the requested number of bytes is read, the error string is available via lastError().

Implements PtexInputHandler.
