RPC 技术详解及应用实践

1. 高尔夫游戏 RPC 接口实现

在 RPC 编程中，我们先来看一个高尔夫游戏的相关接口实现。有两个关键函数StartGolf和EndGame，以及一个PGOLF_GAME_CONTEXT_rundown例程。

RPC STATUS StartGolf ( CHAR *pchPlayerName, PPGOLF_GAME_CONTEXT pphContext ) { *pphContext = NULL; if (iCurrentPlayer >= MAX_PLAYERS) return GOLF_COURSE_TOO_BUSY; // Find a convenient slot for new player for (int i = 0; i < MAX_PLAYERS; i++) { if (Players[i].fSlotTaken == FALSE) break; } *pphContext = &Players[i]; // Set up the slot with proper data Players[i].fSlotTaken = TRUE; Players[i].iPlayerNos = i; // Bump the current usage count iCurrentPlayer++;
