samples: net: echo_server: Avoid warning about truncated writing (6fb34733) · Commits · Wenxi XU / zephyr

The truncation is not possible in practice but add suitable cast to avoid the warning. samples/net/sockets/echo_server/src/tcp.c:297:54: warning: ‘%d’ directive output may be truncated writing between 1 and 10 bytes into a region of size 5 [-Wformat-truncation=] 297 | snprintk(name, sizeof(name), "tcp4[%d]", slot); | ^~~~~~~~~~ Signed-off-by:
