    printing wide characters to strings...

    hello everyone,

    i have a for looop that iterates through an array of bytes, each two byte sequence is a 2 byte wide character, i need to print each two byte sequence to a wchar_t array. I have written some code but i need a few pointers on where to go from here:

    Code:
    	for(i = 0 ; i < name_len ; i++){
    		swprintf(&file_name[i], 1, L"%C",((((u8_t *)p->payload)[i+6] << 8) | ((u8_t *)p->payload)[i+6+1]));
    		printf("%C",file_name[i]);
    	        }
    but that yields a 00000000... etc array

    thanks for your help!

    shouldn't you cast to uint16 before <<8 ?

    also - I'm not sure that using %C in swprintf is a right thing to print wide char
    Have you checked the docs?
    All problems in computer science can be solved by another level of indirection,
    except for the problem of too many layers of indirection.
