Function Documentation

SIO2stream* sio2StreamClose

(

SIO2stream *

_SIO2stream

)

Close and free and SIO2stream, if the SIO2stream still contain some data the data will be freed.

_SIO2stream: A valid SIO2stream pointer.

return a NULL SIO2stream pointer.

References SIO2stream::buf.

Referenced by sio2ResourceExtract(), sio2SoundBufferFree(), sio2SoundBufferGenId(), sio2UrlFree(), and sio2VideoFree().

unsigned char sio2StreamEOF

(

SIO2stream *

_SIO2stream

)

Return whether or not the cursor is at the end of the SIO2stream.

_SIO2stream: A valid SIO2stream pointer.

return 1 or 0 if position in the SIO2stream is at the end of the stream.

References SIO2stream::pos, and SIO2stream::size.

SIO2stream* sio2StreamInit

(

char *

_fname

)

Initialize an empty new SIO2stream memory stream. A SIO2stream is basically acting exactly like a FILE *, at the exception that it is 100% handled in memory speeding up the whole loading process and reduces to a minimum disk access.

_fname: The name of the SIO2stream.

return a new SIO2stream pointer.

References SIO2stream::fname, and sio2StringCpy().

Here is the call graph for this function:

SIO2stream* sio2StreamOpen	(	char *	_fname,
		unsigned char	_rel
	)

Create a new SIO2stream and open the file passed in parameter.

_fname: The filename to open.
_rel: Determine wheter or not the file path is relative to the root of the package.

return a new SIO2stream pointer with the file loaded in the SIO2stream->buf. If the file cannot be found, a NULL SIO2stream pointer will be returned.

References SIO2::app_path, SIO2stream::buf, SIO2stream::cur, SIO2stream::fname, sio2, SIO2_MAX_PATH, sio2StringCpy(), and SIO2stream::size.

Referenced by sio2StreamOpenText().

Here is the call graph for this function:

SIO2stream* sio2StreamOpenText	(	char *	_fname,
		unsigned char	_rel
	)

Basically the same as sio2StreamOpen except that this function should be used for text files only. For binary data use sio2StreamOpen.

_fname: The filename to open.
_rel: Determine wheter or not the file path is relative to the root of the package.

return a new SIO2stream pointer with the file loaded in the SIO2stream->buf. If the file cannot be found, a NULL SIO2stream pointer will be returned.

References SIO2stream::buf, sio2StreamOpen(), and SIO2stream::size.

Here is the call graph for this function:

void sio2StreamParse	(	SIO2stream *	_SIO2stream,
		unsigned int	_n_entry,
		SIO2entry *	_SIO2entry
	)

Parse the SIO2stream based on a dictionnary of SIO2entry, if the SIO2entry string is found the root callback will be called if not the custom callback will be called.

_SIO2stream: A valid SIO2stream pointer.
_n_entry: The number of entry in the SIO2entry dictionnary.
_SIO2entry: The dictionnary to use for parsing.

Here is the call graph for this function:

unsigned int sio2StreamRead	(	SIO2stream *	_SIO2stream,
		void *	_ptr,
		unsigned int	_size_t
	)

Read a specific amount of bytes.

_SIO2stream: A valid SIO2stream pointer with the buffer loaded.
_ptr: Pointer to the memory address to copy the data to.
_size_t: The size of the data to copy.

return the number of bytes copied.

void* sio2StreamReadPtr	(	SIO2stream *	_SIO2stream,
		unsigned int	_size_t
	)

Return the memory address specified by the size passed in parameter.

_SIO2stream: A valid SIO2stream pointer.
_size_t: The size in bytes to read.

return the memory address located in the SIO2stream->buf at the current position.

void sio2StreamReset

(

SIO2stream *

_SIO2stream

)

Reset all the SIO2stream to its original state, and free the buffer.
