NAME

acl_copy_ext − Copies the ACL from internal working space format to a contiguous, persistent form of the ACL

SYNOPSIS

#include <sys/acl.h>
int acl_copy_ext(
        void ∗buf_p,
        acl_t acl_d,
        ssize_t size );

LIBRARY

Security Library (libpacl.a)

PARAMETERS

buf_p
User space to copy the contiguous, persistent for of the ACL into.

acl_d
Specifies 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.
