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
     argument.

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 trans-
			lated 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 manage-
			ment constraints.

STANDARDS

     IEEE Std 1003.1e draft 17 ("POSIX.1e", abandoned)

NAME

     acl_to_text -- convert an ACL to text

LIBRARY

     Standard C Library (libc, -lc)

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 argument acl into a NULL terminated character string.	If the pointer len_p is
     not NULL, then the function shall return 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() for an ACL of type ACL_TYPE_EXTENDED differs from that specified by the POSIX.1e
     standard, and this function cannot translate between formats.

     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 as an argument.

RETURN VALUES

     Upon successful completion, the function shall return a pointer to the long text form of an ACL.  Otherwise, a value of (char*)NULL shall be
     returned and errno shall be set to indicate the error.

ERRORS

     If any of the following conditions occur, the acl_to_text() function shall return a value of (acl_t)NULL and set errno to the corresponding
     value:

     [EINVAL]		Argument acl does not point to a valid ACL.

			The ACL denoted 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 software-imposed memory man-
			agement constraints.
