Linux Access Control Lists library (libacl, -lacl).
SYNOPSIS
acl_t
acl_from_text(const char *buf_p)
DESCRIPTION
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 ac
cepts as input the long text form and short text form of an ACL as de
scribed 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 argu
ment.
RETURN VALUE
Upon successful completion, this function returns a pointer to the work
ing storage. Otherwise, a value of (acl_t)NULL is returned, and errno is
set to indicate the error.
ERRORS
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 al
lowed by the hardware or system-imposed memory management
constraints.
STANDARDS
