RETURN VALUE
On success, getline() and getdelim() return the number of characters
read, including the delimiter character, but not including the termi-
nating null byte. This value can be used to handle embedded null bytes
in the line read.
Your correction is correct, however, I believe I do have a *much*
shorter, simpler and faster solution handy:
http://cvs.mirbsd.de/contrib/code/mirmake/dist/contrib/fgetln.c
The file is also attached to this eMail for convenience.
I originally wrote it for FreeWRT Embedded GNU/Linux because
all existing variants, even the GPL’d ones, were buggy.
