Function Documentation

INBUFFER* blOpenBufferedFile	(	char *	filename,
		int	maxstr
	)

Parameters

[in]	*filename	File name
[in]	maxstr	Max string length in file for buffering

Returns

Pointer to a buffered file

Open a file for buffered input. This allows probe-ahead to look at the contents of the next line without removing it from the input stream.

BOOL blProbeBufferedFile	(	INBUFFER *	bfp,
		char *	string,
		int	length
	)

Parameters

[in]	*bfp	Pointer to a buffered file structure
[in]	length	Size of output string
[out]	*string	Output string read from file

Returns

TRUE: Successful read FALSE: End of file (or error)

Read the next line from a buffered file without removing it from the input stream. Repeated calls will thus return the same string. The next call to ReadBufferedFile will also output the same string, but will remove the line from the input stream. Blank lines in the file will be skipped.

• 07.03.94 Added code to skip blank lines
• 10.03.94 Added call to RePrompt() after blank line

BOOL blReadBufferedFile	(	INBUFFER *	bfp,
		char *	string,
		int	length
	)

Parameters

[in]	*bfp	Pointer to a buffered file structure
[in]	length	Size of output string
[out]	*string	Output string read from file

Returns

TRUE: Successful read FALSE: End of file (or error)

Reads a line from a buffered file (like fgets()). Blank lines in the file will be skipped.
