ACL_FROM_TEXT(3)                   BSD Library Functions Manual                  ACL_FROM_TEXT(3)

NAME
     acl_to_text -- convert an ACL to text

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

SYNOPSIS
     #include <sys/types.h>
     #include <sys/acl.h>

     char *
     acl_to_text(acl_t acl, ssize_t *len_p);

DESCRIPTION
     The acl_to_text() function translates the ACL pointed to by the argument acl into a NULL
     terminated character string.  If the pointer len_p is not NULL, then the function returns
     the length of the string (not including the NULL terminator) in the location pointed to by
     len_p.  The format of the text string returned by acl_to_text() is the long text form
     defined in acl(5).  The ACL referred to by acl is not changed.

     This function allocates any memory necessary to contain the string and returns a pointer to
     the string.  The caller should free any releasable memory, when the new string is no longer
     required, by calling acl_free(3) with the (void*)char returned by acl_to_text() as an argu-
     ment.

RETURN VALUE
     On success, this function returns a pointer to the long text form of the ACL.  On error, a
     value of (char *)NULL is returned, and errno is set appropriately.

ERRORS
     If any of the following conditions occur, the acl_to_text() function returns a value of
     (char *)NULL and sets errno to the corresponding value:

     [EINVAL]           The argument acl is not a valid pointer to an ACL.

                        The ACL referenced by acl contains one or more improperly formed ACL
                        entries, or for some other reason cannot be translated into a text form
                        of an ACL.

     [ENOMEM]           The character string 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)
