ACL_FROM_TEXT(3) Library Functions Manual ACL_FROM_TEXT(3)
acl_from_text — create an ACL from text
Linux Access Control Lists library (libacl, -lacl).
<sys/types.h> <sys/acl.h> acl_t acl_from_text(const char *buf_p)
The 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:
[EINVAL] The argument buf_p cannot be translated into
an ACL.
[ENOMEM] The acl_t to be returned requires more memory
than is allowed by the hardware or system-
imposed memory management constraints.
