Oh.

You're using C then, probably.

You don't need a function to tell it where to store. You can do so yourself.

Code:
char buf[512];

strcpy(buf, "string"); // Store in array pos 0 onward, get "string"
strcpy(buf+1, "aaaaaa"); // Store in array pos 1 onward, get "saaaaaa"
strcpy(buf+6, "hello"); //store in array pos 6 onward, get "saaaaahello"
// or just...
strcat(buf, "hello"); // Always puts it on the end.  Less efficient though!

It's an illustration of what buf+number does, including the fact that it can overwrite existing stuff.

Understanding lseek

I tried to use lseek system call to determine the number of bytes in a file. To do so, I used open system call with O_APPEND flag to open a file. As lseek returns the current offset so I called lseek for opened file with offset as zero and whence as SEEK_CUR. So I guess it must return the number of... (3 Replies)
