printf unsigned char
The correct one is*: printf("%d",x);. This is because of default argument promotions as printf() is variadic function. This means that unsigned char value is always promoted to int . From N1570 (C11 draft) 6.5.2.2/6 Function calls (emphasis min, You can use the following: for (int i = 0 ; i < strlen(tlv_buffer); i++) printf("%02x ",*(tlv_buffer + i));. It will print each byte in hex. edit: use a space to separate and if you want the specific length bytes then specify the length inst
