Counts the number of lines that are not all whitespace and comments using the S\-D\-L\-\_\-\-R\-Wops object pointed to by {\ttfamily rw}. {\ttfamily comment\-\_\-char} indicates the character used for comments. Uses the buffer pointed to by {\ttfamily buffer} to read data in blocks.

Reads a single character using the S\-D\-L\-\_\-\-R\-Wops object pointed to by {\ttfamily rw}. This function reads data in blocks and stores them in the buffer pointed to by {\ttfamily buffer}, so other S\-D\-L\-\_\-\-R\-Wops functions should not be used in conjunction with this function.

The character that was read.

Reads characters using the S\-D\-L\-\_\-\-R\-Wops object pointed to by {\ttfamily rw} into the character array pointed to by {\ttfamily str} (of size {\ttfamily size}) until either the array is full or a new line is encountered. If {\ttfamily comment\-\_\-char} is encountered, all characters from that position till the end of the line are ignored. The new line is not included as part of the buffer. Lines with only whitespace and comments are ignored. This function reads data in blocks and stores them in the buffer pointed to by {\ttfamily buffer}, so other S\-D\-L\-\_\-\-R\-Wops functions should not be used in conjunction with this function.
