[ctypes-users] Using paramflags

[Gary H. <glh...@lb...>]

How are paramflags for the various ctypes types, such as c_char_p setup.  I would like to define a new class, say STRING, which is basically a c_char_p, but is coded as an output only parameter, rather than an input and output parameter.  

I have a number of functions to wrap that accept a const char string, and return an error code plus fill in a pointer to some sort of handle.  I cannot easily use the errcheck function because the results tuple includes the string parameter.

I see Gary Bishop's notes, but creating a new CFuncPtr object seems total overkill for what I need to do.
