Natvis FourCC visualisation syntax

Question

I'm trying to define a .natvis <DisplayString> for a uint32_t type, to show as an array of four characters, which in the Watch window, during debugging, would be expressed a bit like this: (char*)&fourcc,4 .

Unfortunately, natvis doesn't seem to like the & very much - it gets ignored, eg {(char*)&fourcc,4} , {(char*)&{fourcc},4 , {((char*)&)fourcc,4} doesn't work. The documentation does not make it obvious how to perform casts, if it is supported at all.

What am I missing?

Answer 1

Casts are supported, and the syntax is {(char*)&fourcc,4} , ie use the xml entity for '&'.

For best results the na modifier may be used along the array size (ie 4 above) to suppress the showing of the memory address.
