    Command:

    acl_set_qualifier

    
    
    
    

    SYNOPSIS

         #include <sys/types.h>
         #include <sys/acl.h>
    
         int
         acl_set_qualifier(acl_entry_t entry_d, const void *qualifier_p);
    
    
    

    DESCRIPTION

         The acl_set_qualifier() function sets the qualifier of the ACL entry
         indicated by the argument entry_d to the value referred to by the argu-
         ment qualifier_p.  If the value of the tag type in the ACL entry referred
         to by entry_d is ACL_USER, then the value referred to by qualifier_p
         shall be of type uid_t.  If the value of the tag type in the ACL entry
         referred to by entry_d is ACL_GROUP, then the value referred to by
         qualifier_p shall be of type gid_t.  If the value of the tag type in the
         ACL entry referred to by entry_d is a tag type for which a qualifier is
         not supported, acl_set_qualifier() returns an error.
    
         Any ACL entry descriptors that refer to the entry referred to by entry_d
         continue to refer to that entry. This function may cause memory to be
         allocated. The caller should free any releasable memory, when the ACL is
         no longer required, by calling acl_free() with a pointer to the ACL as
         argument.
    
    
    

    RETURN VALUE

         The acl_set_qualifier() function returns the value 0 if successful; oth-
         erwise the value -1 is returned and the global variable errno is set to
         indicate the error.
    
    
    

    ERRORS

         If any of the following conditions occur, the acl_set_qualifier() func-
         tion returns -1 and sets errno to the corresponding value:
    
         [EINVAL]           The argument entry_d is not a valid descriptor for an
                            ACL entry.
    
                            The value of the tag type in the ACL entry referenced
                            by the argument entry_d is neither ACL_USER nor
                            ACL_GROUP.
    
                            The value pointed to by the argument qualifier_p is
                            not valid.
    
         [ENOMEM]           The acl_set_qualifier() function is unable to allocate
                            the memory required for the ACL qualifier.
