Concatenation in C void* char* - 0x6f776c - 10-28-2017

Hello guys

I got this code :

Code:
LPVOID lpvAddr;

lpvAddr = VirtualAlloc(NULL, strlen(jmp_esp), 0x3000, 0x40);

char *x = "\x41\x42\x43";

char *all;

strcat(all , x);

strcat(all , lpvAddr);     // here I got error because can't concate char * with lpvAddr

How can I get the value of lpvaddr in hex (ex:\x00\x22\x33\x44) and append it to <all> variable ?

thanks
