acl_copy_ext(3) — Subroutines
NAME
acl_copy_ext − Copies the ACL from internal working space format to a contiguous, persistent form of the ACL
LIBRARY
Security Library (libpacl.a)
SYNOPSIS
#include <sys/acl.h> int acl_copy_ext(
void ∗buf_p,
acl_t acl_d,
ssize_t size);
PARAMETERS
buf_pUser space to copy the contiguous, persistent for of the ACL into.
acl_dSpecifies the working storage, internal format ACL to copy.
sizeIndicates the size of the buffer pointed to by buf_p.
DESCRIPTION
NOTE: This function is based on Draft 13 of the POSIX P1003.6 standard.
The acl_copy_ext() function copies the contents of the ACL in internal working space format, pointed to by acl_d, into the buffer pointed to by buf_p. The ACL copied into the buffer is in contiguous, persistent formatxi and is not NULL terminated.
RETURN VALUES
Upon successful completion, the acl_copy_ext function returns the size of the ACL copied. Otherwise, a value of -1 is returned and errno is set to indicate the error.
ERRORS
If any of the following conditions occur, the acl_copy_ext() function sets errno to the corresponding value:
[EINVAL]The size parameter is zero or negative. The ACL referenced by acl_d contains one or more improperly formed ACL entries, or for some other reason can not be translated into contiguous format.
[ERANGE]The size parameter is greater than 0, but smaller than the ACL to be copied.
