Creating New DataTypes from a Script

[jarodcsaxberg]

Is there a way to create a new DataType from a script? Basically using the DataTypeManager's addDataType() function with a custom DataType that's created in the script, attempting to replicate the Data Type Manager -> New -> Typedef... from the GUI. I am working with an InternetOpenW function that is not recognized by ghidra, so it decompiles to undefined InternetOpenW(void). The goal is to be able to replicate the process of updating the function signature from a script through the use of custom DataTypes for any that Ghidra doesn't recognize, and the Function class's updateFunction() function. For example, creating the type HINTERNET that refers to void*

Solved this by referencing #1916 and #993. Sample python code below.

from ghidra.app.util.cparser.C import CParser
from ghidra.program.model.data import DataTypeConflictHandler

dtm = currentProgram.getDataTypeManager()
parser = CParser(dtm)

new_dt = parser.parse("typedef void* HINTERNET;")

transaction = dtm.startTransaction("Adding new data")
dtm.addDataType(new_dt, None)
dtm.endTransaction(transaction, True)
