acl_from_text(3) BSD Library Functions Manual acl_from_text(3)
NAME
acl_from_text -- create an ACL from text
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <sys/types.h>
#include <sys/acl.h>
acl_t
acl_from_text(const char *buf_p);
DESCRIPTION
The acl_from_text() function converts the text form of an ACL referred to
by buf_p into the internal working structure for ACLs, appropriate for
applying to files or manipulating.
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 as an argument.
IMPLEMENTATION NOTES
The ACL_TYPE_EXTENDE text format differs from the POSIX.1e format, and
this function will not translate between formats.
RETURN VALUES
Upon successful completion, the function shall return a pointer to the
internal representation of the ACL in working storage. Otherwise, a
value of (acl_t)NULL shall be returned, and errno shall be set to indi-
cate the error.
ERRORS
If any of the following conditions occur, the acl_from_text() function
shall return a value of (acl_t)NULL and set errno to the corresponding
value:
[EINVAL] Argument buf_p cannot be translated into an ACL.
[ENOMEM] The ACL working storage requires more memory than is
allowed by the hardware or system-imposed memory man-
agement constraints.
