NAME
sm2file - shared-memory linked list data extraction test program
SYNOPSIS
sm2file
DESCRIPTION
sm2file stress-tests shared-memory linked list data extraction by retrieving and deleting all text file lines inserted into a shared-memory
linked list that is the root object of a PSM partition named "file2sm".
The operation of sm2file echoes the cyclical operation of file2sm: the EOF lines inserted into the linked list by file2sm punctuate the
writing of files that are copies of file2sm's original source text file. The name of each file written by sm2file is file_copy_cycleNbr,
where cycleNbr is, in effect, the count of EOF lines encountered in the linked list up to the point at which the writing of this file
began.
sm2file may catch up with the data ingestion activity of file2sm, in which case it blocks (taking the file2sm test semaphore) until the
linked list is no longer empty.
EXIT STATUS
0 sm2file has terminated.
FILES
No configuration files are needed.
ENVIRONMENT
No environment variables apply.
