ACL_DUP(3) FreeBSD Library Functions Manual ACL_DUP(3) NAME acl_dup - duplicate an ACL LIBRARY Standard C Library (libc, -lc) SYNOPSIS #include <sys/types.h> #include <sys/acl.h> acl_t acl_dup(acl_t acl); DESCRIPTION The acl_dup() function returns a pointer to a copy of the ACL pointed to by the argument acl. 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. Any existing ACL pointers that refer to the ACL referred to by acl shall continue to refer to the ACL. IMPLEMENTATION NOTES FreeBSD's support for POSIX.1e interfaces and features is still under development at this time. RETURN VALUES Upon successful completion, this function shall return a pointer to the duplicate ACL. 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_init() function shall return a value of (acl_t)NULL and set errno to the corresponding value: [EINVAL] Argument acl does not point to a valid ACL. [ENOMEM] The acl_t to be returned requires more memory than is allowed by the hardware or system-imposed memory management constraints. SEE ALSO acl(3), acl_free(3), acl_get(3), posix1e(3) STANDARDS POSIX.1e is described in IEEE POSIX.1e draft 17. Discussion of the draft continues on the cross-platform POSIX.1e implementation mailing list. To join this list, see the FreeBSD POSIX.1e implementation page for more information. HISTORY POSIX.1e support was introduced in FreeBSD 4.0, and development continues. AUTHORS Robert N M Watson FreeBSD 14.1-RELEASE-p8 January 28, 2000 FreeBSD 14.1-RELEASE-p8
