Retrieves the class symbol structure for the specified object class name.

#include <odmi.h>CLASS_SYMBOL odm_mount_class ( ClassName)
char *ClassName;
The odm_mount_class subroutine retrieves the class symbol structure for a specified object class. The subroutine can be called by applications (for example, the ODM commands) that have no previous knowledge of the structure of an object class before trying to access that class. The odm_mount_class subroutine determines the class description from the object class header information and creates a CLASS_SYMBOL object class that is returned to the caller.
The object class is not opened by the odm_mount_class subroutine. Calling the subroutine subsequent times for an object class that is already open or mounted returns the same CLASS_SYMBOL object class.
Mounting a class that links to another object class recursively mounts to the linked class. However, if the recursive mount is unsuccessful, the original odm_mount_class subroutine does not fail; the CLASS_SYMBOL object class is set up with a null link.
| Item | Description |
|---|---|
| ClassName | Specifies the name of an object class from which to retrieve the class description. |
Upon successful completion, a CLASS_SYMBOL is returned. If the odm_mount_class subroutine is unsuccessful, a value of -1 is returned and the odmerrno variable is set to an error code.
Failure of the odm_mount_class subroutine sets the odmerrno variable to one of the following error codes:
