    Command:

    acl_create_entry

    
    
    
    

    SYNOPSIS

         #include <sys/types.h>
         #include <sys/acl.h>
    
         int
         acl_create_entry(acl_t *acl_p, acl_entry_t *entry_p);
    
    
    

    DESCRIPTION

         The acl_create_entry() function creates a new ACL entry in the ACL
         pointed to by the contents of the pointer argument acl_p.  On success,
         the function returns a descriptor for the new ACL entry via entry_p.
    
         This function may cause memory to be allocated.  The caller should free
         any releasable memory, when the new ACL is no longer required, by calling
         acl_free(3) with (void*)*acl_p as an argument.  If the ACL working stor-
         age cannot be increased in the current location, then the working storage
         for the ACL pointed to by acl_p may be relocated and the previous working
         storage is released. A pointer to the new working storage is returned via
         acl_p.
    
         The components of the new ACL entry are initialized in the following
         ways: the ACL tag type component contains ACL_UNDEFINED_TAG, the quali-
         fier component contains ACL_UNDEFINED_ID, and the set of permissions has
         no permissions enabled. Any existing ACL entry descriptors that refer to
         entries in the ACL continue to refer to those entries.
    
    
    

    RETURN VALUE

         The acl_create_entry() function returns the value 0 if successful; other-
         wise 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_create_entry() function
         returns -1 and sets errno to the corresponding value:
    
         [EINVAL]           The argument acl_p is not a valid pointer to an ACL.
    
         [ENOMEM]           The ACL working storage requires more memory than is
                            allowed by the hardware or system-imposed memory man-
                            agement constraints.
    
    
    

    STANDARDS
