If there is any line that starts with a digit (after possible whitespace), it has to print either the data or an error. If it doesn't, then there is no line whose first non-whitespace character would satisfy g_ascii_isdigit(c) or it does not end up in the list. This means either - g_ascii_isdigit(c) does not evaluate to TRUE for digits on your system - g_slist_prepend() does not work - g_slist_reverse() does not work - the file looks different than you sent Which one is it? > (I tried to print a field > every time a new line was about to be read in the while-loop). > Furthermore, I wonder if the test, > if(end == start) > failfield = "Latitude";, > can conclude that the string was converted correctly with > g_ascii_strtod().

Unless the file contain one of the few possible cases of concatenated floating point numbers that can be parsed back -- these can be catched by checking whether *end is space or '\0'. But this does not matter at all. Either way you get *some* output, either data or errors (or both in the case of trailing garbage). You must get some output even if g_ascii_strtod() and strtol() return completely random values. So I just don't believe you. Period.
