I think it is possible after slight code modification.
I have found that pwgen.c containing main() function just parses command
line, sets up few variables indicating modes and conditions under which
passwords will be generated and calls pwgen() function which finally
does the work. I can imagine to make a library from objects. This
library on one hand can be used to build a tool and to be ready for
general use on the other hand. It would be necessary to update manual
(man page) to document the interface.
This is how it gets compiled so far:
<snip>
ligi at marvin ~/doc/project/sun/oss/wrk/pwgen/pwgen-2.06 $ make
gcc -c -DHAVE_DRAND48=1 -DHAVE_GETOPT_LONG=1 -DHAVE_GETOPT_H=1 -g -O2
pwgen.c -o pwgen.o
gcc -c -DHAVE_DRAND48=1 -DHAVE_GETOPT_LONG=1 -DHAVE_GETOPT_H=1 -g -O2
pw_phonemes.c -o pw_phonemes.o
...
gcc -c -DHAVE_DRAND48=1 -DHAVE_GETOPT_LONG=1 -DHAVE_GETOPT_H=1 -g -O2
sha1num.c -o sha1num.o
gcc -o pwgen pwgen.o pw_phonemes.o pw_rand.o randnum.o sha1.o sha1num.o
</snip>
This is how the worker function gets called:
<snip>
pwgen(buf, pw_length, pwgen_flags);
</snip>
where buf is a buffer to which passwords will be generated and pw_length
and pwgen_flags specifies the generation mode.
Would it usable?

Martin
