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

Inputs

INBUFFER *bfp Pointer to a buffered file structure
int length Size of output string

Outputs

char *string Output string read from file

Returns

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

Description

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.
