i'm receiving message through socket in c written buffer. message has terminator ( @@ ) added end know when stop writing buffer, however, buffer larger message. there way write , not including terminator, throwing away rest of buffer? maybe position pointer? char *pos; file* fp = fopen("tempfile", "w+"); pos = strstr(buffer, "@@"); pos = '\0'; // maybe stop writing null? fwrite(buffer, 1, buf_size /*too big*/, fp); fclose(fp); i need size of portion of buffer contains message, or maybe write file character. either way work. statement fwrite(buffer, 1, buf_size, fp) write buf_size bytes, regardless of actual content of buffer , regardless if contains '\0' considered "string termination". way tell fwrite correct number of elements write; , can calculated through pointer arithmetics: fwrite(buffer, 1, pos-buffer, fp) of course, you'll have check if pos != null , on; think straight forward.
