QTMLGetVolumeRootPath4

QuickTime 3 For Windows Programmers

QTMLGetVolumeRootPath

The QTMLGetVolumeRootPath routine takes a Windows path and returns that portion of it which points to the volume root.



 
OSErr QTMLGetVolumeRootPath(

          char *fullPath,

          char * volumeRootPath,

          unsigned long volumeRootLen);

fullPath: Specifies the path being passed in.
volumeRootPath: Specifies where this routine writes the volume root path.
volumeRootLen: Specifies the length of the volumeRootPath buffer, so the routine knows not to write past the end of your buffer.

This routine works in the following way. If you pass in



 
c:\some folder\test.mov

it will return c:\

and if you pass in



 
\\my_server\shared_folder\mystuff\test.mov

it will return



 
\\my_server\shared_folder\

This is useful when you need to call Windows routines, such as GetVolumeInformation , which take a volume root path as an argument.
