ACL_COPY_INT (3) Library Functions Manual ACL_COPY_INT (3)

NAME

acl_copy_int — copy an ACL from external to internal representation

LIBRARY

Linux Access Control Lists library (libacl, -lacl).

SYNOPSIS

#include <sys/types.h>
#include <sys/acl.h>

acl_t

acl_copy_int ( const void *buf_p );

DESCRIPTION

The acl_copy_int () function copies an exportable, contiguous, persistent form of an ACL, pointed to by buf_p , to the internal representation.

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_copy_int () as an argument.

RETURN VALUE

Upon success, the acl_copy_int () function returns a pointer that references the ACL in working storage. On error, a value of (acl_t)NULL is returned, and errno is set appropriately.

ERRORS

If any of the following conditions occur, the acl_copy_int () function returns a value of (acl_t)NULL and sets errno to the corresponding value:

[EINVAL]

The buffer pointed to by the argument buf_p does not contain a valid external form ACL.

[ENOMEM]

The ACL working storage requires more memory than is allowed by the hardware or system-imposed memory management constraints.

STANDARDS

IEEE Std 1003.1e draft 17 (“POSIX.1e”, abandoned)
