sscanf strings
Author
I'm trying to sscanf a string from a buffer, this string is inclosed within a pair of "
The output should be the same as buffer:
CODE:
char buffer[600];
buffer = "8 10000 \"Pistol\" \"Basic Weapon\nLow Fire Rate\" weapons/pistol.bmp 255 0 255 1000 25 5";
unsigned int clipsize, maxammo, reload, firerate;
char name[20], description[256];
char* iconfile;
int r, g, b;
int damage;
sscanf(buffer, "%d %d %s %s %s %d %d %d %d", &clipsize, &maxammo, name, description, iconfile, &r, &g, &b, &reload, &firerate, &damage);
printf("%d %d \"%s\" \"%s\" %s %d %d %d %d", clipsize, maxammo, name, description, iconfile, r, g, b, reload, firerate, damage);
- You can't assign a string literal to an array like that. An array has, unlike a pointer, a fixed address. The assignment is trying to change that address to that of the string literal.
- You didn't allocate memory for *iconfile - your code will crash.
- scanf treats whitespace as separators. Like it or not, %s will only ever read a single 'word'.
- What you really want is to use a scanset, associated with character anchors:
"%d %d \"%[^\"]\" \"%[^\"]\" %s %d %d %d %d %d %d". Refer to your C library documentation for more details.
sscanf = time * money
As an interesting corollary,
girls = buffer overflow.
Also, there's some flag you can give to sscanf that causes it to not treat whitespace as a delimiter, but I can't remember what it is. Regardless, sscanf is prone to buffer overflows and general badness - I'd consider using a std::stringstream and << >> operators.
