MakeSureDirectoryPathExists

MakeSureDirectoryPathExists
Function

Creates all the directories in the specified path, beginning with the
root.

BOOL WINAPI MakeSureDirectoryPathExists(
__in          PCSTR DirPath
);

Parameters

DirPath

A valid path name. If the final component of the path is a directory, not a
file name, the string must end with a backslash (/) character.

Return Value

If the function succeeds, the return value is TRUE.

If the function fails, the return value is FALSE. To retrieve extended error
information, call GetLastError.

Remarks

Each directory specified is created, if it does not already exist. If only
some of the directories are created, the function will return FALSE.

This function does not support Unicode strings. To specify a Unicode path,
use the SHCreateDirectoryEx
function.

#pragma comment(lib,"imagehlp.lib")
int _tmain(int argc, _TCHAR* argv[])
{
//Creates all the directories in the specified path
MakeSureDirectoryPathExists("C://test//aa//a.txt");//成功
MakeSureDirectoryPathExists("C://test//aa//bb//a.txt");//成功
MakeSureDirectoryPathExists("C://test//aa//cc//");//成功
MakeSureDirectoryPathExists(".//test//");//成功
MakeSureDirectoryPathExists("..//test//");//成功
MakeSureDirectoryPathExists("./test2/");//不成功
MakeSureDirectoryPathExists("C:/test2/aa/a.txt");//不成功
MakeSureDirectoryPathExists("C://test2");//不成功
return 0;
}
