NAME

       acl_valid - Checks an ACL for validity

LIBRARY

       Security Library (libpacl.a)

SYNOPSIS

       #include <sys/acl.h>
       int acl_valid(	   acl_t acl_d,      acl_entry_t *entry_p);

PARAMETERS

       Specifies the working storage internal representation of an ACL.  Pointer to the location that holds a returned ACL entry.

DESCRIPTION

       NOTE:  This function is based on Draft 13 of the POSIX P1003.6 standard.

       The acl_valid() function checks the ACL for validity.  An ACL is invalid if one or more of the following conditions are violated: The three
       required entries (ACL_USER_OBJ, ACL_GROUP_OBJ, and ACL_OTHER_OBJ) must appear exactly once in an ACL of type ACL_TYPE_ACCESS, and in a non-
       empty ACL of type ACL_TYPE_DEFAULT or ACL_TYPE_DEFAULT_DIR.  The ACL must not contain a duplicate entry.  An entry is duplicated if another
       entry in the same ACL has the same entry tag type and the same tag qualifier (sameness or difference in permissions is not relevant).

RETURN VALUES

       Upon successful completion, the acl_valid() function returns a value of 0 (zero).  Otherwise, a value of -1  is	returned,  and	the  errno
       global variable is set to indicate the error.

ERRORS

       For  the following condition, the acl_valid() function sets the location specified by the entry_p parameter with the value of the ACL entry
       for which one or more duplicates exist elsewhere in the ACL.  The ACL contains entries that are not unique.

       For the following conditions, the acl_valid() function sets the location indicated by the entry_p parameter to the NULL value.	The  acl_d
       parameter does not refer to a valid ACL.

       One or more of the required entries is not present.

acl_set_fd(3)						     Library Functions Manual						     acl_set_fd(3)

NAME

       acl_set_fd - Sets the ACL on the file or directory designated by the file descriptor

LIBRARY

       Security Library (libpacl.a)

SYNOPSIS

       #include <sys/acl.h>
       int acl_set_fd(	    int fd;	 acl_type_t type_d;	 acl_t acl_d);

PARAMETERS

       Refers  to  the	open  file  descriptor	of  the  file or directory to set the ACL on.  Designates the type of ACL to set: ACL_TYPE_ACCESS,
       ACL_TYPE_DEFAULT, or ACL_TYPE_DEFAULT_DIR.  Working storage internal representation of the ACL that is being set.

DESCRIPTION

       NOTE:  This function is based on Draft 13 of the POSIX P1003.6 standard.

       Given a file descriptor to a file or directory, the acl_set_fd() function sets the designated ACL.  The type of ACL being set is determined
       by the type_d parameter.  If acl_d is NULL then the designated ACL is removed from the designated file or directory. The entry pointer used
       by the acl_get_entry() function becomes undefined after a call to the acl_set_fd() function.

RETURN VALUES

       Upon successful completion, the acl_set_fd() function returns a value of 0 (zero).  Otherwise, a value of -1 is returned and errno  is  set
       to indicate the error.

ERRORS

       If any of the following conditions occur, the acl_set_fd() function sets errno to the corresponding value:

       The  required  access to the file was denied.  The fd argument is not a valid file descriptor.  The acl_d argument does not contain a valid
       ACL.

       Argument type_d does not contain a valid ACL type number.  The directory or file system that would contain the new ACL cannot  be  extended
       or the file system is out of file allocation resources.	The argument type_d indicates a default ACL, and fd does not point to a directory.
       The designated file or directory resides on a file system that does not support ACLs.  The process does not have  the  appropriate  permis-
       sions to perform the operation.

       The  setting  and changing of ACLs have been disabled by the system administrator.  The designated file or directory resides on a read-only
       file system.
