| .SH "DESCRIPTION" |
| .BR security_class_to_string () |
| returns a string name for class |
| .IR tclass , |
| or NULL if the class is invalid. The returned string must not be modified or freed. |
| |
| .BR security_av_perm_to_string () |
| returns a string name for the access vector bit |
| .I av |
| of class |
| .IR tclass , |
| or NULL if either argument is invalid. The returned string must not be modified or freed. |
| |
| .BR security_av_string () |
| computes a full access vector string representation using |
| .I tclass |
| and |
| .IR av , |
| which may have multiple bits set. The string is returned in the memory pointed to by |
| .IR result , |
| and should be freed by the caller using |
| .BR free (3). |
| |
| .BR string_to_security_class () |
| returns the class value corresponding to the string name |
| .IR name , |
| or zero if no such class exists. |
| |
| .BR mode_to_security_class () |
| returns the class value corresponding to the specified |
| .IR mode , |
| or zero if no such class exists. |
| |
| .BR string_to_av_perm () |
| returns the access vector bit corresponding to the string name |
| .I name |
| and security class |
| .IR tclass , |
| or zero if no such value exists. |
| |
| .BR print_access_vector () |
| displays an access vector in human-readable form on the standard output |
| stream. |
| . |
| .SH "RETURN VALUE" |
| .BR security_av_string () |
| returns zero on success or \-1 on error with |
| .I errno |
| set appropriately. |
| .BR print_access_vector () |
| does not return a value. All other functions return zero or NULL on error. |
| . |
| .SH "ERRORS" |
| .TP |
| .B EINVAL |
| A class or access vector argument is not recognized by the currently loaded policy. |
| |
| .TP |
| .B ENOMEM |
| An attempt to allocate memory failed. |
