Thanks for the quick and exhaustive answer. I'll try that.

Pointer C types don't exist separately from the pointed-to type anymore, so it doesn't make sense to TYPEDEF: something like SQLSMALLINT* anymore. You can get the same effect by removing the pointers: TYPEDEF: short SQLSMALLINT SQLSMALLINT* will then automatically be equivalent to short* . -Joe -- Download Intel® Parallel Studio Eval Try the new software tools for yourself.

Re: [Factor-talk] *-in-c-type-name
I've been working with the ODBC code with this change for a few months now: TYPEDEF: short* SQLSMALLINT* but am not knowledgeable enough why it would be wrong. It was early in my Factor learning process, and I can't swear I tested every data type.

While parameters with a char* pointer type used to be treated specially and would automatically convert Factor strings to C strings and back, this is no longer the case. A separate type, c-string, is now used to automatically convert strings in the FFI. This is discussed in the "C strings" article of the FFI docs: http://docs.factorcode.org/content/article-c-strings.html The fix for odbc will probably be to update some parameters that take char* parameters (or typedefs thereof) to now take c-string parameters. -Joe-- Download Intel® Parallel Studio Eval Try the new software tools for yourself.

[Factor-talk] *-in-c-type-name
Hi there, I've tried to use the odbc-vocab in the newest factor source. I get this interesting error: 17: TYPEDEF: void* SQLSMALLINT* ^ *-in-c-type-name So I think, maybe the pointer-types work automatically now and comment this thing. Now it loads fine, but on running I get: Generic word underlying>> does not define a method for the string class. Dispatching on object: "DSN=TEST_DSN" Any hints how to resolve this? I didn't find the docs for these changes in alien.syntax. Ben -- Download Intel® Parallel Studio Eval Try the new software tools for yourself.
