Nope,  does support an unlimited amount of bits by using
arrays of unsigned chars. You might want to recheck its implementation. :)

No problem!

The difference between sys/bitstring.h and the package I propose is that
bitstring.h implements a bit array within one unit of data storage (unsigned
char, 1 byte, 8 bits), while my package uses an array of units (array of
unsigned long integers, usually 32 or 64 bits EACH). This means that BSD's bit
array can't be longer that 8 bits, while mine is limited by memory size only.

Oh, yes, you are right. I was able to reproduce this problem. The name of the
header guard needs to be changed. Thank you very much for pointing it out.

Well, obviously not entirely as complete but the BSDs (and libbsd
otherwise) do have something like .

BTW, I noticed when I checked the implementation that you are using
HAVE_BITFIELD_H as the header macro protector, but that's actually a
bad idea, as with the typical autoconf based build-system that macro
will already be defined if the build-system does something like
AC_CHECK_HEADERS([bitfield.h]), which means the contents will be
secluded.

  Description : bit array manipulation library

bitfield is a library of functions for creating, modifying and destroying bit
fields (or bit arrays), i.e. series of zeroes and ones spread across an array of
storage units (unsigned long integers).

Bit array is a simple data structure used in a wide range of software (starting
from Linux kernel), yet there is no library that would provide this
functionality, so every package has to reinvent the wheel.

As the author, I would be willing to maintain the Debian package. This is my
first submission, so I would need a sponsor.
