PWCACHE(3)                386BSD Programmer's Manual                PWCACHE(3)

NAME
     pwcache - cache password and group entries

SYNOPSIS
     userfromuid(uid_t uid, int nouser)

     groupfromgid(gid_t gid, int nogroup)

DESCRIPTION
     This interface is not part of the C library.  It has been placed in the
     Berkeley utility library, libutil, as it is used by several standard
     utilities.

     The userfromuid() function returns the user name associated with the
     argument uid. The user name is cached so that multiple calls with the
     same uid do not require additional calls to getpwuid(3).  If there is no
     user associated with the uid, a pointer is returned to an ASCII
     representation of the uid, unless the argument nouser is non-zero, in
     which case a NULL pointer is returned.

     The groupfromgid() function returns the group name associated with the
     argument gid. The group name is cached so that multiple calls with the
     same gid do not require additional calls to getgrgid(3).  If there is no
     group associated with the gid, a pointer is returned to an ASCII
     representation of the gid, unless the argument nogroup is non-zero, in
     which case a NULL pointer is returned.

HISTORY
     The userfromid() and groupfromid() functions are currently under
     development.
