ACL_FROM_TEXT(3) BSD Library Functions Manual ACL_FROM_TEXT(3)
acl_from_text — create an ACL from text
Linux Access Control Lists library (libacl, -lacl).
#include <sys/types.h>
#include <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 call‐
ing 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 appropri‐
ately.
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.
