Get address of the specified field using the type information
ea - address of the strcture
field_name - name of the structure field
If the database contains a structurue at the specified ea and the
type information is present, this function will return the address of the
structure field.
long get_field_ea(long ea, string field_name);
For example:
.data:00413060 errtable dd 1 ; oscode
.data:00413060 dd 16h ; errnocode
msg("address is: %x\n", _errtable.errnocode);
prints 413064.
The "_errtable.errnocode" expression is essentially a shortcut for:
get_field_ea(get_name_ea_simple("_errtable"), "errnocode")
