lpszVolumeMountPoint

lpszVolumeMountPoint is a parameter name used in Windows API documentation to refer to a pointer to a null-terminated string that identifies a volume mount point. A mount point is a directory on a file system that acts as the access point for another volume; the mounted volume is reachable through that directory path rather than a separate drive letter. In this context, lpszVolumeMountPoint specifies the path of the mount point that the API should operate on.

In practice, functions that work with mount points receive lpszVolumeMountPoint as an input string. For example, in the GetVolumeNameForVolumeMountPoint function family, the caller provides the mount point path through lpszVolumeMountPoint, and the function writes the corresponding volume name (such as a GUID-based path) into an output buffer. The exact character type of the string depends on the API variant being used (Unicode or ANSI), with the W versions operating on wide-character strings and the A versions on narrow-character strings.

The naming convention lpszVolumeMountPoint reflects Windows Hungarian notation, where lpsz indicates a pointer to a null-terminated string, and VolumeMountPoint conveys the semantic meaning of the string. When working with mount points, developers typically ensure that the directory designated as a mount point exists and is appropriate for mounting a volume, using related APIs to create, mount, or dismount as needed. Understanding lpszVolumeMountPoint helps interpret Windows API signatures and the flow of information between a mount point path and its associated volume identifier.
