dbplus_open — Open relation file
Opens the given relation file.
Can be either a file name or a relative or absolute path name. This will be mapped in any case to an absolute relation file path on a specific host machine and server.
On success a relation file resource (cursor) is returned which must be used in any subsequent commands referencing the relation. Failure leads to a zero return value, the actual error code may be asked for by calling dbplus_errno().
