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

NAME         top

     acl_to_text — convert an ACL to text

LIBRARY         top

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

SYNOPSIS         top

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

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

DESCRIPTION         top

     The acl_to_text() function translates the ACL pointed to by the argu‐
     ment 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         top

     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         top

     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.
