Question

I have const binary data that I need insert to buffer
for example

 char buf[] = "1232\0x1";

but how can do it when binary data is at first like below

 char buf[] = "\0x11232";

compiler see it like a big hex number
but my perpose is

 char buf[] = {0x1,'1','2','3','2'};

Answer 1

You can use compile-time string concatenation:

char buf[] = "\x01" "1232";

However, with a 2-digit number after \x it also works without:

char buf[] = "\x011232";
