WRITEUPDATEUNLOCK[X] Procedures
Syntax for C Programmers
•
CEXTDECS (through 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.
•
The function value returned by WRITEUPDATEUNLOCK[X], which indicates the
condition code, can be interpreted by
_status_lt(), _status_eq(), or
_status_gt() (defined in the file tal.h).
