|ACL_FROM_TEXT(3)||Library Functions Manual||ACL_FROM_TEXT(3)|
acl_to_text() function translates the ACL pointed to by the argument acl into a
NULLterminated character string. If the pointer len_p is not
NULL, then the function returns the length of the string (not including the
NULLterminator) 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
the (void*)char returned by
acl_to_text() as an argument.
(char *)NULLis returned, and errno is set appropriately.
acl_to_text() function returns a value of
(char *)NULLand sets errno to the corresponding value:
- 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.
- The character string to be returned requires more memory than is allowed by the hardware or system-imposed memory management constraints.
