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_free(3) 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:

       [EINVAL]           The argument buf_p cannot be translated into an ACL.

       [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 (“POSIX.1e”, abandoned)
