 		 #128154 - Table of function pointers
Responding to: ???'s previous message
Andy Neil said:


The problem comes if the Linker cannot deduce the function call tree.



If you locate the table in CODE space the linker can reconstruct correctly the call tree with no problems. I use function tables in my protocol handler to associate the command received with the function to call to execute the command.

Look at application note AN129 from Keil :
