    NAME

    acl_from_text
    
     - create an ACL from text
    
     
    

    LIBRARY

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

    SYNOPSIS

       #include <sys/types.h>
       #include <sys/acl.h>
    acl_t acl_from_text (const char *buf_p);
     

    DESCRIPTION

    The acl_from_text ();
    function converts the text form of the ACL referred to by buf_p into the internal form of an ACL and returns a pointer to the working storage that contains the ACL. The acl_from_text ();
    function accepts as input the long text form and short text form of an ACL as described in acl(5).

    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_free3 with the (void*)acl_t returned by acl_from_text ();
    as an argument.  

    RETURN VALUE

    On success, this function returns a pointer to the working storage. On error, a value of (acl_t)NULL is returned, and errno is set appropriately.  

    ERRORS

    If any of the following conditions occur, the acl_from_text ();
    function returns a value of (acl_t)NULL and sets errno to the corresponding value:

    Bq Er EINVAL
    The argument buf_p cannot be translated into an ACL.
    Bq Er ENOMEM
    The acl_t to be returned requires more memory than is allowed by the hardware or system-imposed memory management constraints.

     

    STANDARDS

    IEEE Std 1003.1e draft 17 (lqPOSIX.1erq, abandoned)
