NAME

       getuserattr, getusernam, getuseruid, free_userattr, setuserattr, enduserattr, fgetuserattr - get user_attr entry

SYNOPSIS

       cc [ flag... ] file... -lsecdb  -lsocket  -lnsl [ library... ]
       #include <user_attr.h>

       userattr_t *getuserattr(void);

       userattr_t *getusernam(const char *name);

       userattr_t *getuseruid(uid_t uid);

       void free_userattr(userattr_t *userattr);

       void setuserattr(void);

       void enduserattr(void);

       userattr_t *fgetuserattr(FILE *f);

       The  getuserattr(),  getusernam(),  and	getuseruid()  functions each return a user_attr(4) entry. Entries can come from any of the sources
       specified in the nsswitch.conf(4) file. The getuserattr() function enumerates user_attr entries. The getusernam() function searches  for  a
       user_attr  entry with a given user name name. The getuseruid() function searches for a user_attr entry with a given user ID uid. Successive
       calls to these functions return either successive user_attr entries or NULL.

       The fgetuserattr() function does not use nsswitch.conf but reads and parses the next line from the stream f. This stream is assumed to have
       the format of the user_attr files.

       The free_userattr() function releases memory allocated by the getusernam(), getuserattr(), and fgetuserattr() functions.

       The internal representation of a user_attr entry is a userattr_t structure defined in <user_attr.h> with the following members:

       char  *name;	  /* name of the user */
       char  *qualifier;  /* reserved for future use */
       char  *res1;	  /* reserved for future use */
       char  *res2;	  /* reserved for future use */
       kva_t *attr;	  /* list of attributes */

       The setuserattr() function "rewinds" to the beginning of the enumeration of user_attr entries.  Calls to getusernam() may leave the enumer-
       ation in an indeterminate state, so setuserattr() should be called before the first call to getuserattr().

       The enduserattr() function may be called to indicate that user_attr processing is complete; the library may then close any  open  user_attr
       file, deallocate any internal storage, and so forth.

       The  getuserattr() function returns a pointer to a userattr_t if it successfully enumerates an entry; otherwise it returns NULL, indicating
       the end of the enumeration.

       The getusernam() function returns a pointer to a userattr_t if it successfully locates the requested entry; otherwise it returns NULL.

USAGE

       The getuserattr() and getusernam() functions both allocate memory for the pointers they return. This memory should be deallocated with  the
       free_userattr() function.

       Individual attributes can be referenced in the attr structure by calling the kva_match(3SECDB) function.

WARININGS

       Because the list of legal keys is likely to expand, code  must be written to ignore unknown key-value pairs without error.
