PathGetArgsW 函数 (shlwapi.h)

查找给定路径中的命令行参数。

语法

LPCWSTR PathGetArgsW(
  [in] LPCWSTR pszPath
);

参数

[in] pszPath

类型： PTSTR

指向包含要搜索的路径的最大长度MAX_PATH以 null 结尾的字符串的指针。

返回值

类型： PTSTR

返回指向以 null 结尾的字符串的指针，如果成功，该字符串包含路径的参数部分。

如果路径中没有参数，则函数返回指向输入字符串末尾的指针。

如果为函数提供 NULL 参数，则返回 NULL。

注解

不应在用户或注册表) (的泛型命令路径模板上使用此函数，而应仅在应用程序知道格式正确的模板上使用。

示例

#include <windows.h>
#include <iostream.h>
#include "Shlwapi.h"

void main( void )
{
    // Path_1 to search for file arguments (2 arguments):
    char buffer_1[ ] = "test.exe temp.txt sample.doc"; 
    char *lpStr1;
    lpStr1 = buffer_1;
    
    // Path_2 to search for file arguments (3 arguments):
    char buffer_2[ ] = "test.exe 1 2 3"; 
    char *lpStr2;
    lpStr2 = buffer_2;
    
    // Path_3 to search for file arguments (3 arguments):
    char buffer_3[ ] = "test.exe sample All 15"; 
    char *lpStr3;
    lpStr3 = buffer_3;
    
    // Path_4 to search for file arguments (no arguments):
    char buffer_4[ ] = "test.exe"; 
    char *lpStr4;
    lpStr4 = buffer_4;
    
    cout << "The path passed to the function was : " << lpStr1 <<
            "\nThe arg(s)found in path 1 were      : " << PathGetArgs(lpStr1) << endl;
    
    cout << "\nThe path passed to the function was : " << lpStr2 <<
            "\nThe arg(s)found in path 2 were      : " << PathGetArgs(lpStr2) << endl;
    
    cout << "\nThe path passed to the function was : " << lpStr3 <<
            "\nThe arg(s)found in path 3 were      : " << PathGetArgs(lpStr3) << endl;
    
    cout << "\nThe path passed to the function was : " << lpStr4 <<
            "\nThe arg(s)found in path 4 were      : " << PathGetArgs(lpStr4) << endl;
}

OUTPUT:
===========
The path passed to the function was : test.exe temp.txt sample.doc
The arg(s)found in path 1 were      : temp.txt sample.doc

The path passed to the function was : test.exe 1 2 3
The arg(s)found in path 2 were      : 1 2 3

The path passed to the function was : test.exe sample All 15
The arg(s)found in path 3 were      : sample All 15

The path passed to the function was : test.exe
The arg(s)found in path 4 were      :
===========
