Declaring utility functions for the user mapping plug-in (C programming language)

You must declare four required utility options for the user mapping plug-in.

FSUMlogErrorMSg, FSUMaddUMOption, FSUMallocate, and FSUMdeallocate are required utility functions for the user mapping plug-in. The optional utility functions can be useful when you develop a user mapping plug-in. You obtain the pointers of the utility functions from the FSUMPluginUtilities structure in the FSUMPluginInit function.
