int QlgStatvfs64(Qlg_Path_Name_T *path,
struct statvfs64 *buf
Service Program Name: QP0LLIB1The QlgStatvfs64() function, like the statvfs64() function, gets status information about the file system that contains the file named by the path argument. The difference is that the QlgStatvfs64() function takes a pointer to a Qlg_Path_Name_T structure, while statvfs64() takes a pointer to a character string.
Limited information about the path parameter is provided here. For more information about the path parameter and for a discussion of other parameters, authorities required, return values, and related information, see statvfs()--Get File System Information.
The following example gets information about a file system.
