Re: reading a line through scanf

I especially like it for use with text files.
The only possible drawback, is that you get no feedback
on whether or not the lines are longer than LENGTH.

int nonblank_line(FILE *fd, char *line)
{
int rc;

do {
rc = fscanf(fd, "%" xstr(LENGTH) "[^\n]%*[^\n]", line);
if (!feof(fd)) {
getc(fd);
}
} while (rc == 0 || rc == 1 && blank(line));
return rc;
}

int blank(char *line)
{
while (isspace(*line)) {
++line;
}
return *line == '\0';
}
