ACL_FROM_TEXT(3) Library Functions Manual ACL_FROM_TEXT(3)
acl_to_text — convert an ACL to text
Linux Access Control Lists library (libacl, -lacl).
<sys/types.h> <sys/acl.h> char * acl_to_text(acl_t acl, ssize_t
*len_p)
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.
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.
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.
