c语言hex字符串转byte数组

例：”0C B1 15 02 C0 27 01 20 ” –> {0x0c, 0xb1, 0x15, 0x02, 0xc0, 0x27, 0x01, 0x20}

static int hex2byte(char *dst, char *src) {
    while(*src) {
        if(" " == *src) {
            src++;
            continue;
        }
        sscanf(src, "%02X", dst);
        src += 2;
        dst++;
    }
    return 0;
}
