       int crsetgroups(cred_t *cr, int ngroups, gid_t gids);

INTERFACE LEVEL
       Solaris DDI specific (Solaris DDI).

PARAMETERS
       cr
				pointer to the user credential structure

       uid, ruid, euid, suid
				new user id, real, effective and saved user id

       gid, rgid, egid, sgid
				new  group id, real, effective and saved group
				id

       ngroups
				number of groups in the group array

       gids
				pointer to array of new groups

DESCRIPTION
       The user credential is a shared, read-only, ref-counted data structure.
       Its  actual  size  and  layout  are  subject  to	 change. The functions
       described in this page allow the programmer to retrieve fields from the
       structure and to initialize newly allocated credential structures.

       crgetuid(),  crgetruid(),  and  crgetsuid()  return,  respectively, the
       effective, real, and saved user id from the user credential pointed  to
       by cr.

       crgetgid(),  crgetrgid(),  and  crgetsgid()  return,  respectively, the
       effective, real, and saved group id from the user credential pointed to
       by cr.

       crgetzoneid()  returns  the zone id from the user credential pointed to
       by cr.

       crgetgroups() returns the group list of the user credential pointed  to
       by cr.

       crgetngroups()  returns	the  number  of	 groups in the user credential
       pointed to by cr.

       crsetresuid() sets the real, effective and saved user id. All  but  one
       can be specified as -1, which causes the original value not to change.

       crsetresgid()  sets the real, effective and saved group id. All but one
       can be specified as -1, which causes the original value not to change.

       crsetugid() initializes the real, effective and saved user  id  all  to
       uid. It initializes the real, effective, and saved group id all to gid.

       crsetgroups()  sets  the	 number	 of  groups  in the user credential to
       ngroups and copies the groups from gids	to  the	 user  credential.  If
       ngroups is 0, gids need not point to valid storage.

       It  is  an  error  to call this any of the crset*() functions on a user
       credential structure that was newly allocated.

RETURN VALUES
       The crget*() functions return the requested information.

       The crset*id() functions return 0 on success and -1 if any of the spec‐
       ified  ids  are	invalid.  The  functions might cause a system panic if
       called on a user credential structure that is referenced by other parts
       of the system.

CONTEXT
       These functions can be called from user and kernel contexts.
