ACL_FROM_TEXT(3) BSD Library Functions Manual ACL_FROM_TEXT(3)
acl_to_text — convert an ACL to text
Linux Access Control Lists library (libacl, -lacl).
#include <sys/types.h>
#include <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 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.
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.
