ANTLR3_API void antlr3Fclose

(

ANTLR3_FDSC

fd

)

Close an operating system file and free any handles etc.

Here is the caller graph for this function:

ANTLR3_API ANTLR3_FDSC antlr3Fopen	(	pANTLR3_UINT8	filename,
		const char *	mode
	)

Open an operating system file and return the descriptor We just use the common open() and related functions here.

Later we might find better ways on systems such as Windows and OpenVMS for instance. But the idea is to read the while file at once anyway, so it may be irrelevant.
