OSS_PID_NULL_ Procedure
OSS_PID_NULL_ Procedure
Summary

Syntax for TAL Programmers
Parameters
OSS Considerations
Summary
The OSS_PID_NULL_ procedure returns a null OSS process ID.
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
oss-pid returned value
INT (32)
is a null OSS process ID.
OSS Considerations
A null OSS process ID can be passed to a procedure such as
PROCESS_GETINFOLIST_ to indicate that the OSS process ID parameter is not
present (an alternative to omitting the parameter). The value of the null OSS process
ID can change from one RVU to another.
#include <cextdecs(OSS_PID_NULL_)>
__int32_t OSS_PID_NULL_ ( void );
oss-pid := OSS_PID_NULL_;
