Summary
The CHECKCLOSE procedure is called by a primary process to close a designated file
in its backup process.
The backup process must be in the monitor state (that is, in a call to
CHECKMONITOR) for the CHECKCLOSE to be successful. The call to
CHECKCLOSE causes the CHECKMONITOR procedure in the backup process to call
the file-system CLOSE procedure for the designated file.
Syntax for C Programmers
This passive backup procedure is not supported in C programs. For a comparison of
active backup and passive backup, refer to the
Guardian Programmer’s Guide.
Syntax for TAL Programmers

filenum input
INT:value
