First of all, in your declarations, you have only declared three *pointers*
to chars, not three strings. No memory has been allocated for the strings
yet. So you must either declare the strings as:
char sdf[10], ghj[10], klm[10];
or must use alloc or malloc to allocate memory for the strings.
Secondly, you can't just set a string value by using "=" (except in the
declaration). You must use something like strcpy to set the string:
char sdf[10], ghj[10], klm[10];
strcpy (sdf, "ABC");
strcpy (ghj, "XYZ");
Finally, to put the strings together, there are a number of ways you could
do this. One is just to concatenate them:
strcpy (klm, sdf); // Copies contents of sdf ("ABC") to klm
strcat (klm, ghj); // Appends contents of ghj ("XYZ") to klm, giving
"ABCZXY"
To do this with StrPrintF, you could do something like the following:
StrPrintF(klm, "%s%s", sdf, ghj);
The first parameter is the destination variable, the second is a format
string (%s represents a string, so %s%s represents two strings with nothing
between them), and the other variables are used to populate the format
string. Since the format string is %s%s, the function is expecting two
strings to be found in the list of variables. The value of sdf gets plugged
into the first %s and the value of ghj gets plugged into the second %s.
Hope this helps,

Subject: StrPrintF example needed
I'm trying to figure out some of the details of the StrPrintF function:
suppose:
char *sdf, *ghj, *klm;
sdf = "ABC";
ghj = "XYZ";
How could I put sdf en ghj into another variable klm (becoming klm ==
"ABCXYZ") using the StrPrintF function? Or are there better ways of
managing 'strings'?
Thx in advance,
--PieterJ.
