Windows操作系统常用API函数

_CRTIMP void __cdecl _splitpath (const char *, char *, char *, char *, char *);

_CRTIMP void __cdecl _makepath (char *, const char *, const char *, const char *, const char *);

WINBASEAPI BOOL WINAPI SetCurrentDirectory ( LPCSTR lpPathName );

WINBASEAPI DWORD WINAPI GetModuleFileName ( HMODULE hModule, LPSTR lpFilename, DWORD nSize );

 

示例：

 CString cTemp;
 char FileName[MAX_PATH];
 ::GetModuleFileName(NULL,FileName,MAX_PATH);
 
 char drive[_MAX_DRIVE];
 char dir[_MAX_DIR];
 _splitpath(FileName,drive,dir,NULL,NULL);
 //设置当前目录
 _makepath(FileName,drive,dir,NULL,NULL);
 SetCurrentDirectory(FileName);
 //sprintf(FileName,"SetUp.INI");
 _makepath(FileName,drive,dir,"setup",".INI");
