priv_set_t *priv_str_to_set(const char *buf, const char *set, \ const char **endptr);
priv_str_to_set() takes a string of privilege names that are specified in buf. priv_str_to_set() returns a set of privilege values that can be combined with one of the four privilege sets. **endptr can be used to debug parsing errors.
Note that the following keywords can be included in buf:
“all” indicates all defined privileges. “all,!priv_name,...” enables you to specify all privileges except the indicated privileges.
Constructions that use “priv_set, “!priv_name,...” subtract the specified privilege from the specified set of privileges. Do not use “!priv_name,...” without first specifying a set because with no privilege set to subtract from, the construction subtracts the specified privileges from an empty set of privileges and effectively indicates no privileges.
“none” indicates no privileges.
“basic” indicates the set of privileges that are required to perform operations that are traditionally granted to all users on login to a standard UNIX operating system.
