The ring pipe utilities are intended to provide mechanisms for non ringbuffer aware software to access ring buffers. These utilities are also used by the high level access libraries to provide access to remote ringbuffers via proxy rings.
There are two ring pipe utilities:
Accepts data from a ring buffer and transmits it to the program's stdout file descriptor.
Accepts data from the program's stdin file descriptor and places it in the ring buffer.
The ringtostdout command can be used to hoist data out of ring buffers to a command or filter that is not aware of the NSCL Data acquisition system. It is a key element of the pipeline that ships data to SpecTcl, as well as a key component of the networked data distribution system (with stdout redirected to a socket). For detailed usage information see the ringtostdout reference pages.
The stdintoring command can be used to allow a non NSCLDAQ aware program or pipeline to be a producer for a ring buffer. This command is also a key component of the networked data distribution system (with stdin redirected to a socket). For detailed information, see the stdintoring reference material.
