/* Find the next text line.
|
|
|
|
This routine scans the text provided buffer until it encounters
|
|
either a linefeed (\\n) or a null byte (\\0). If it finds a line
|
|
feed, it returns a pointer to the *next* line. If it finds a null
|
|
byte, a pointer to that null byte is returned.
|
|
|
|
Using this routine you can easily scan a text buffer line for line,
|
|
just use a look like this:
|
|
|
|
while((p = text_find_next_line(p)) != '\\0') ...
