Error Messages

The following error message is produced when this function is used incorrectly:

“Argument to __builtin_edspage() is not the address of an object in extended data space.”

The argument must be an explicit object address.

For example, if obj is object in an executable or read-only section, the following syntax is valid:

uint16_t page = __builtin_edspage(&obj);
