pair before starting a series of write operations to a file open with paired access.
FILE_GETSYNCINFO_ returns a file’s synchronization block so that it can be sent to
the backup process in a checkpoint message.The FILE_GETSYNCINFO_ procedure
supersedes the GETSYNCINFO Procedure (Superseded by FILE_GETSYNCINFO_
Procedure). Unlike the GETSYNCINFO procedure, this procedure can be used with
Format 2 files as well as with other files.

Note. Typically, FILE_GETSYNCINFO_ is not called directly by application programs.
Instead, it is called indirectly by CHECKPOINT.
#include <cextdecs(FILE_GETSYNCINFO_)>
short FILE_GETSYNCINFO_ ( short filenum
, short * infobuf
, short infosize );
error := FILE_GETSYNCINFO_ ( filenum ! i
,infobuf ! o
,infomax ! i
,infosize ); ! o
