The getpwent(3) and getgrent(3) implementations maintain some internal iterator state. Interleaved calls to functions which do passwd/group lookups using a key, such as getpwnam(3), would in some cases clobber this state, causing a subsequent getpwent() or getgrent() call to restart iteration from the beginning of the database or to terminate early. This is particularly troublesome in programming environments where execution of green threads is interleaved within a single OS thread. Take care to restore any iterator state following a keyed lookup. The "files" provider for the passwd database was already handling this correctly, but "compat" was not, and both providers had this problem when accessing the group database.

FreeBSD
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
