ACL_COPY_INT(3) BSD 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 argu- ment.

RETURN VALUE Upon success, the acl_copy_int() function returns a pointer that refer- ences 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 man- agement constraints.

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