Convert char* to upper case

[RishiD]

Hi,

For some reason I am blanking this Friday morning. I have a class
constructor call Point as shown below. Trying to figure out how I can
make the arguments passed in all upper case before I set the member
variables.

Thanks for the insight.

Point(const char* name,
const char* description,
const char* iomid,
const char* address,
const char* type,
Event* event)
{
m_strName = name;
m_strDesc = description;
m_strAddress = address;
m_strType = type;
m_strParentName = iomid;
m_Event = event;
}

Starting with posting code that seems a little like C++ to
comp.lang.c? (It has indeed been a lengthy week.)

There's no builtin C function to do this, but you could write one
using the builtin toupper() for characters. Alternatively, there
might be a C++ way to do this, if you are indeed writing C++ as it
seems.

....which makes me think you're using C++, so I've cross-posted this
reply to comp.lang.c++, and set followups to that group.

In C, you'd probably write a function that calls toupper() in a loop -
but in C++ there may be a more C++y way to do it.

[Remainder of your article retained, for clc++'s convenience. Hi guys,
long time no see.]

[OT] That would be, surprisingly, the toupper(c) or toupper(begin,end)
services provided in <ctype>

}

#include <ctype.h>

void up(char *q)
{
unsigned char c;

while (*q) { c = *q; *q = toupper(c); q++; }

return;
}

Also your function specifies "const char *". You might want to adhere to that.

Go back and read Roberto's message again, this time
paying attention to the text he quoted and responded to.

The C++ part? toupper(begin,end) is new to me if it's valid at all,
regardless of which language is used.

Oh, provided by a ctype class, not provided by any <ctype> header...?

You are correct. I thought he was responding in general, not specifically to
the C++ part. Part of that may be due to the fact that I don't generally
think in any C++ mode while i'm in this NG.

#include <ctype.h>

void up(char *q)
{
unsigned char c;

while (*q) { c = *q; *q = toupper(c); q++; }

return;
}

Also your function specifies "const char *". You might want to adhere to
that.

Especially since this can cause bad things to happen using the above code:
char *ptr = "test";
up(ptr);

[Still-off-topic] Beginning to get beyond my depth, (no books at hand
now.) I believe it is provided by the standard headers, but somehow
linked to (buried under?) the locale selection mechanisms.

There is also a toupper(c, loc) that will convert c to upper case IFF
it is a lower case character in locale loc.
