MACRO to capitalize first letter of a word in header.

[dissectcode]

I know about toupper() and tolower() but I need to capitalize (or de-capitalize)the first letter of a word in a header file. I know there are no preprocessor functions that do that but is there another way?

Wait a minute ... why do you need the cast? The cast suggests that either the "name" argument to the macro or the "anum" field of the structure is not intrinsically the proper pointer type. Is it a void*?

In general, if you want run-time resolution of pointer types you have a table where each entry contains a void* pointer and an enumeration for all of the possible types that might be pointed to. You then have a big switch on the enumeration value with a case for each possible type. Within each case you explicitly cast the pointer to right kind of pointer type. However, realize that you have no safety net. You have almost no hope of getting a compiler warning/error if you mess up one of those cases by casting to the wrong type.

donbock is right..
can you give us please exactly how you need this to work?
I am very curious... what must the name and Name be?
It seems to be that you must follow A LOT OF naming conventions... which of course is only a burden for your mind... things that the compiler cannot check can be tricky..

I think what I am trying to do can only be done using actual C code in functions since the name will depend on run-time inputs. I am using to it access HW registers. Please look at how the word "name" has certain letters in CAPS, or not.

#define REG_ADDR            ((void *) (0x00054000))
 
#define REG_CASTADDR   ((Name *)(REG_ADDR))
 
#define RD_REG(name, reg)    NAME##_CASTADDR->name##reg.myUint)
#define WR_REG(name, reg, val)  /
((NAME_REG_BASE->name##reg.myUint) = val)
 

and then from a C program I call the macros:

int registerState = RD_REG(Regtest, Interrupt_stat);
 

So I need it to turn into :

REGTEST_CASTADDR->regtestInterrupt_stat.myUint;
 

It looks messy but I made is as general as possible
