# Build wolfSSL with -DWOLFSSL_EMNET using the clean-room shim in
# tests/emnet/ (IP/IP.h + emnet_shim.c), link a non-blocking TLS 1.3
# handshake test, and run it. The test exercises the WOLFSSL_EMNET
# path in wolfSSL_LastError() and asserts that would-block events
# surface as WANT_READ/WANT_WRITE and the handshake completes,
# guarding against regressions in the emNET error-translation logic.
