<h2>Coding philosophy</h2>



<p>

Most of the code was kept in as few files as possible, with the smallest possible number of parameters.

Whenever more parameters are required, it should always be possible to give <code>NULL</code> or <code>0</code>

as values to get a default behavior.

</p>



<p>

For example, the <code>read_line_alloc</code> takes many parameters:

<pre class="code">

int read_line_alloc(void* in, DataSourceType in_type, char** line,

			int* sz_line, int i0, char from, char to, int keep_fromto,

			char interest, int* interest_count);

</pre>

The only <em>really</em> mandatory parameters are obviously <code>in</code> and <code>line</code>.

All others can be set to <code>NULL</code>, <code>0</code> or <code>'\0'</code>:<br/>

Calling <code><strong>read_line_alloc(f, DATA_SOURCE_FILE, &line, NULL, 0, 0, 0, 0, 0, NULL);</strong></code> will

read bytes from <code>f</code> into <code>line</code> starting from current position in <code>f</code> until

a newline character (or end-of-file) has been reached. <code>line</code> will be allocated but its size will

not be returned (only the number of characters read). No special character will be counted during file reading.

</p>



<p>

So, if you are not too sure what to put as a parameter, just zero it, it should be fine! :)
