From what I can gather, you are trying to use a C/C++ function in MATLAB which uses a struct and are facing issues while using the structure.
Another option is to translate a Ctypedefto a Haskelltypealias. Perhaps this would be a pretty faithful translation, and it would only introduce a type constructor. Perhaps the type would be easier to use, without having to unwrap, especially use of instances. Always treat nested structs as s...
Note that the type name in atypeofconstruct cannot contain storage-class specifiers such asexternorstatic. However, type qualifiers such asconstorvolatileare allowed. For example, the following code is invalid because it declaresexternin thetypeofconstruct: Copy Copied to Clipboard Error: Could not...
This is because the C version is saying it has const characters and I am writing to them, so in order to avoid confusion (and probably compilation warnings or errors), I drop the const part. If you really need the const part, it is even simpler: Just use the pointer returned by the...

typedef struct { bytes[3]; } U24; You can write arithmetic routines to manipulate (assign, add, subtract) these U24s either in C or assembler. Or, if you're willing to perhaps lose a few instructions, do the math in U32s and cast the result back. In the second case, y...

The C standard doesn't really disallow it from what I can see. What's more, the Windows headers actually use this, as an example, the LARGE_INTEGER and ULARGE_INTEGER types. prettyprint typedef union _LARGE_INTEGER { struct { DWORD LowPart; LONG HighPart; } DUMMYSTRUCTNAME; struct ...
