sscanf(strOneLine,"%x: %x %x %x %x\n", &Data.Reg[i], &Data.Reg[i+0x08],
&Data.Reg[i+0x0F], etc, etc, )
will work. if you put in the static characters like i did for you, it will
read them and ignore them.
my favorate method for reading in a unknown variable is with delimiters like
this
DATA:
TEST|002334|LEFT|CENTER|14.665|TRUE|
call
char DATA[6][500];
// clear data so you can tell if a null is recieved
strcpy(DATA[0],"");strcpy(DATA[1],"");
strcpy(DATA[2],"");strcpy(DATA[3],"");
strcpy(DATA[4],"");strcpy(DATA[5],"");
sscanf(strOneLine,"%[^|]|%[^|]|%[^|]|%[^|]|%[^|]|%[^|]|", &DATA[0],&DATA[1],
&DATA[2]&DATA[3]&DATA[4]&DATA[5]);
Data.Reg[i]=atoi(DATA[0]);
NOTE: you have to have something between the delimiters, even if just a
space else the entire remaining data will be corupt.
NOTE data recieved in my example must be less then 500 characters in length
else corruption.
NOTE this method allows for multiplatform use because 16bit vs 32 bit will
gather different numbers using the automatic method. my method allows for a
check before assigning the data.
most common delimiters are the | "," ~
i only use sscanf in my programs. and i am using MSVC++ 6.0 right now. it is
very stable and reliable if you know the rules. (rules about pointers,
redirection,memory allocation, etc.)
