| 释义 | GetDefaultPrinter 语法： BOOL GetDefaultPrinter( __in LPTSTR pszBuffer, __inout LPDWORD pcchBuffer ); GetDefaultPrinter功能 该GetDefaultPrinter函数检索为本地计算机上的当前用户默认打印机的名称。 参数 pszBuffer [in] 阿一个缓冲区，它接收一个空结束的字符串，默认打印机的名称的指针。如果该参数为NULL，则函数失败和变量指向pcchBuffer返回所需的缓冲区大小的字符。 pcchBuffer [ in , out ] 在输入，指定大小，字符的pszBuffer缓冲区。在输出，收到的大小，以字符的打印机的名称字符串，包括终止空字符。 返回值 如果函数成功，返回值是一个非零值和变量指向pcchBuffer包含复制到pszBuffer缓冲区的字符数，包括终止空字符。 如果函数失败，返回值是零。 ValueMeaning ERROR_INSUFFICIENT_BUFFERThe pszBuffer缓冲区太小。该变量所指向的pcchBuffer包含字符所需的缓冲区大小。 ERROR_FILE_NOT_FOUNDThere没有默认打印机。 要求： 最低支持：client－Windows 2000专业版 最低支持server－Windows 2000服务器 HeaderWinspool.h(头文件：winuser.h) LibraryWinspool.lib Unicode和ANSI namesGetDefaultPrinterW(Unicode)和GetDefaultPrinterA(ANSI)的 参见 Printing and Print Spooler Overview Printing and Print Spooler 函数 SetDefaultPrinter 如果有任何问题和意见，请发送给微软(wsddocfb@microsoft.com) 生成日期：2009年7月11日 ＝＝英文原文＝＝GetDefaultPrinter Function The GetDefaultPrinter function retrieves the printer name of the default printer for the current user on the local computer. Syntax BOOL GetDefaultPrinter( __in LPTSTR pszBuffer, __inout LPDWORD pcchBuffer ); Parameters pszBuffer [in] A pointer to a buffer that receives a null-terminated character string containing the default printer name. If this parameter is NULL, the function fails and the variable pointed to by pcchBuffer returns the required buffer size, in characters. pcchBuffer [in, out] On input, specifies the size, in characters, of the pszBuffer buffer. On output, receives the size, in characters, of the printer name string, including the terminating null character. Return Value If the function succeeds, the return value is a nonzero value and the variable pointed to by pcchBuffer contains the number of characters copied to the pszBuffer buffer, including the terminating null character. If the function fails, the return value is zero. ValueMeaning ERROR_INSUFFICIENT_BUFFERThe pszBuffer buffer is too small. The variable pointed to by pcchBuffer contains the required buffer size, in characters. ERROR_FILE_NOT_FOUNDThere is no default printer.
