Thread: sprintf(len+id ?

Hi,

I'm trying to translate some C code to java and trying to understand some code so I could write it. Now I'm not a C expert, so don't laugh at me

I'm trying to figure out what the line below does:

Code:

sprintf(id + len,"%08x",(uint32_t)(timems & 0xffffffff));

Where 'id' is u_char and 'len' is integer. Does he copy the resulting char array to id[len] or something ?

You basically got the idea.

id is the output string. It seems the author wanted that output to start at the 'len'th character in that array.
