ATMI C Function Reference

tpclose(3c)

Name

tpclose()—Routine for closing a resource manager.

Synopsis

#include <atmi.h>
int tpclose(void)

Description

tpclose() tears down the association between the caller and the resource manager to which it is linked. Since resource managers differ in their close semantics, the specific information needed to close a particular resource manager is placed in a configuration file.

If a resource manager is already closed (that is, tpclose() is called more than once), no action is taken and success is returned.

In a multithreaded application, a thread in the TPINVALIDCONTEXT state is not allowed to issue a call to tpclose().

Return Values

Upon failure, tpclose() returns -1 and sets tperrno to indicate the error condition.

Errors

Upon failure, tpclose() fails and sets tperrno to one of the following values:

[TPERMERR]

A resource manager failed to close correctly. More information concerning the reason a resource manager failed to close can be obtained by interrogating a resource manager in its own specific manner. Note that any calls to determine the exact nature of the error hinder portability.

[TPEPROTO]

tpclose() was called in an improper context (for example, while the caller is in transaction mode).

[TPESYSTEM]

A BEA Tuxedo system error has occurred. The exact nature of the error is written to a log file.

[TPEOS]

An operating system error has occurred.
