| Type |
Specifies the type of attribute expected. Valid types are defined in the usersec.h file and include:
- SEC_INT
- The format of the attribute is an integer.
For the getuserattr subroutine, the user should supply a pointer to a defined integer variable. For the putuserattr subroutine, the user should supply an integer.
- SEC_CHAR
- The format of the attribute is a null-terminated character string.
- SEC_LIST
- The format of the attribute is a series of concatenated strings, each null-terminated. The last string in the series is terminated by two successive null characters.
- SEC_BOOL
- The format of the attribute from getuserattr is an integer with the value of either 0 (false) or 1 (true). The format of the attribute for putuserattr is a null-terminated string containing one of the following strings: true, false, yes, no, always, or never.
- SEC_COMMIT
- For the putuserattr subroutine, this value specified by itself indicates that changes to the named user are to be committed to permanent storage. The Attribute and Value parameters are ignored. If no user is specified, the changes to all modified users are committed to permanent storage.
- SEC_DELETE
- The corresponding attribute is deleted from the database.
- SEC_NEW
- Updates all the user database files with the new user name when using the putuserattr subroutine.
