FILE* fmemopen	(	void *	buf,
		size_t	size,
		const char *	mode
	)

A BSD port of the fmemopen Linux method using funopen.

man docs for funopen: https://developer.apple.com/library/mac/#documentation/Darwin/Reference/ManPages/man3/funopen.3.html

This method is ported from ingenuitas' python-tesseract project.

You must call fclose on the returned file pointer or memory will be leaked.

Parameters

buf	The data that will be used to back the FILE* methods. Must be at least size bytes.
size	The size of the buf data.
mode	The permitted stream operation modes.

Returns

A pointer that can be used in the fread/fwrite/fseek/fclose family of methods. If a failure occurred NULL will be returned.
