Public Member Functions | |
FileHandleDataStream (const String &name, FILE *handle, uint16 accessMode=READ) | |
Create named stream from a C file handle. More... | |
FileHandleDataStream (FILE *handle, uint16 accessMode=READ) | |
Create stream from a C file handle. More... | |
~FileHandleDataStream () override | |
void | close () override |
Close the stream; this makes further operations invalid. More... | |
bool | eof () const override |
Returns true if the stream has reached the end. More... | |
size_t | read (void *buf, size_t count) override |
Read the requisite number of bytes from the stream, stopping at the end of the file. More... | |
void | seek (size_t pos) override |
Repositions the read point to a specified byte. More... | |
void | skip (long count) override |
Skip a defined number of bytes. More... | |
size_t | tell () const override |
Returns the current byte offset from beginning. More... | |
size_t | write (const void *buf, size_t count) override |
Write the requisite number of bytes from the stream (only applicable to streams that are not read-only) More... | |

enum | AccessMode { READ = 1 , WRITE = 2 } |
Common subclass of DataStream for handling data from C-style file handles.
Create stream from a C file handle.
Ogre::FileHandleDataStream::FileHandleDataStream | ( | const String & | name, |
FILE * | handle, | ||
uint16 | accessMode = READ |

Create named stream from a C file handle.

override |
|
overridevirtual |
Close the stream; this makes further operations invalid.
Implements Ogre::DataStream.
|
overridevirtual |
Returns true if the stream has reached the end.
Implements Ogre::DataStream.
|
overridevirtual |
Read the requisite number of bytes from the stream, stopping at the end of the file.
buf | Reference to a buffer pointer |
count | Number of bytes to read |
Implements Ogre::DataStream.
|
overridevirtual |
Repositions the read point to a specified byte.
Implements Ogre::DataStream.
|
overridevirtual |
Skip a defined number of bytes.
This can also be a negative value, in which case the file pointer rewinds a defined number of bytes.
Implements Ogre::DataStream.
|
overridevirtual |
Returns the current byte offset from beginning.
Implements Ogre::DataStream.
|
overridevirtual |
Write the requisite number of bytes from the stream (only applicable to streams that are not read-only)
buf | Pointer to a buffer containing the bytes to write |
count | Number of bytes to write |
