pvaClientCPP

pvaClient is a synchronous client interface to pvAccess, which is callback based. pvaClient is thus easier to use than pvAccess itself.

See documentation/pvaClientCPP.html for details.

Building

If a proper RELEASE.local file exists one directory level above pvaClientCPP then just type:

make

If RELEASE.local does not exist then look at configure/RELEASE for directions for how to build.
