ACL_FROM_TEXT(3)

NAME
acl_from_text - create an ACL from text

LIBRARY
libc

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 indicate 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 management constraints.

STANDARDS
POSIX.1e is described in IEEE POSIX.1e draft 17.
