Convert operand to a symbolic constant (for the explanations of 'ea' and 'n' please see op_bin()) enumid - id of enumeration type serial - serial number of the constant in the enumeration The serial numbers are used if there are more than one symbolic constant with the same value in the enumeration. In this case the first defined constant get the serial number 0, then second 1, etc. There could be 256 symbolic constants with the same value in the enumeration.
success op_enum(long ea, int n, long enumid, long serial);
