    NAME

    acl_set_qualifier
    
     - set the qualifier of an ACL entry
    
     
    

    LIBRARY

    Linux Access Control Lists library (libacl, -lacl).
     
    

    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 argument 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

    Rv -std acl_set_qualifier  

    ERRORS

    If any of the following conditions occur, the acl_set_qualifier ();
    function returns -1 and sets errno to the corresponding value:

    Bq Er 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.

    Bq Er ENOMEM
    The acl_set_qualifier ();
    function is unable to allocate the memory required for the ACL qualifier.
