Linux Access Control Lists library (libacl, -lacl).
acl_from_text(const char *buf_p);
acl_from_text() function converts the text form of the ACL referred to by buf_p into the internal form of an ACL and returns a pointer to the working storage that contains the ACL. The
acl_from_text() function accepts as input the long text form and short text form of an ACL as described in acl(5).
This function may cause memory to be allocated. The caller should free any releasable memory, when the new ACL is no longer required, by calling acl_free(3) with the (void*)acl_t returned by
acl_from_text() as an argument.
On success, this function returns a pointer to the working storage. On error, a value of
(acl_t)NULL is returned, and errno is set appropriately.
If any of the following conditions occur, the
acl_from_text() function returns a value of
(acl_t)NULL and sets errno to the corresponding value:
The argument buf_p cannot be translated into an ACL.
The acl_t to be returned requires more memory than is allowed by the hardware or system-imposed memory management constraints.
