Summary
MOVEX moves data between extended data segments without the need for absolute
addressing; it serves both privileged and nonprivileged users.
Syntax for C Programmers
•
CEXTDECS (via the included file TNSINTH) defines 32-bit values as the typedef
__int32_t which for TNS and TNS/R compiles is defined as
long and for TNS/E
compiles is defined as
int.
Syntax for TAL Programmers
Parameters
error returned value
INT
returns a file-system error code indicating the outcome of the call:
0 Successful call; the specified data was moved.
2Either
source-seg-id or dest-seg-id specified a nonexistent
extended data segment, or the destination data segment has read-only
access.
22 One of the parameters specifies an address that is out of bounds.
