Get one wide byte of the program at 'ea'. ea - linear address returns: value of byte. If byte has no value then returns 0xFF Some processors may access more than 8bit quantity at an address. These processors have 32-bit byte organization from the IDA's point of view. To check if a byte has a value, use is_loaded(ea).
long get_wide_byte(long ea); #define byte(ea) get_wide_byte(ea)
