I may have put it a bit incorrectly, > In that case, your expectations of the getgrXXX functions are wrong.
but I don't think so. I am looking if a user belongs to a group, either as their primary or secondary one. So when using getgrXXX() I check to see if a user (whose primary, passwd-supplied, gid does not match the gid of the group) is listed as a member. In CYGWIN that does not work because the information is missing from the group file. Anton Lavrentiev Contractor NIH/NLM/NCBI
