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
User space to copy the contiguous, persistent for of the ACL into. Specifies the working storage, internal format ACL to copy. Indicates 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: 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 con- tiguous format. The size parameter is greater than 0, but smaller than the ACL to be copied. RELATED INFORMATION

NAME
acl_copy_ext -- copy an ACL from internal to external representation LIBRARY
Linux Access Control Lists library (libacl, -lacl). SYNOPSIS
#include <sys/types.h> #include <sys/acl.h> ssize_t acl_copy_ext(void *buf_p, acl_t acl, ssize_t size); DESCRIPTION
The acl_copy_ext() function copies the ACL pointed to by acl from system-managed space to the user managed space pointed to by buf_p. The size parameter represents the size in bytes of the buffer pointed to by buf_p. The format of the ACL placed in the buffer pointed to by buf_p is a contiguous, persistent data item, the format of which is unspecified. It is the responsibility of the invoker to allocate an area large enough to hold the copied ACL. The size of the exportable, contiguous, persistent form of the ACL may be obtained by invoking the acl_size() function. Any ACL entry descriptors that refer to an entry in the ACL referenced by acl continue to refer to those entries. Any existing ACL pointers that refer to the ACL referenced by acl continue to refer to the ACL. RETURN VALUE
Upon success, this function returns the number of bytes placed in the buffer pointed to by buf_p. On error, a value of (ssize_t)-1 is returned and errno is set appropriately. ERRORS
If any of the following conditions occur, the acl_copy_ext() function returns a value of (ssize_t)-1 and sets errno to the corresponding value: [EINVAL] The size parameter is zero or negative. The argument acl is not a valid pointer to an ACL. The ACL referenced by acl contains one or more improperly formed ACL entries, or for some other reason cannot be trans- lated into the external form of an ACL. [ERANGE] The size parameter is greater than zero but smaller than the length of the contiguous, persistent form of the ACL. STANDARDS
