It helps you write robust EPICS PV Access (PVA) client applications in C++ using pvxs, handling gets, puts, monitors, and RPC with correct typing and operation lifetimes.
Use the pvxs-client skill to write a small C++ program that connects to a PV name from the command line and performs a GET, a PUT, and a continuously running MONITOR until SIGINT is received.

Use the pvxs::client API to manage context, build typed pvxs::Value trees, and execute asynchronous PVA operations like Get, Put, Monitor, and RPC with proper lifetime management.
PV Access monitor callbacks should enqueue work from the event callback and drain updates using pop() with correct exception handling to ensure network operations transfer only changed fields safely.
Build pvRequest-style field selection and record options to specify exact PV data requirements, enabling efficient network operations by transferring only marked fields and tracked changes.
Yes, you can build and manipulate PV value trees using TypeDef and normative types including NTScalar, NTEnum, NTTable, NTNDArray, and NTURI for correct typed data interactions.
Manage operation lifetimes safely by leveraging pvxs::client context management and handling asynchronous operation results with appropriate timeouts to prevent premature cleanup.
Yes, pvxs supports synchronous and asynchronous RPC workflows alongside PVA Get, Put, Monitor, Info, and Connect scenarios, providing proper result handling and timeout management.
