Question

我用tlv格式读取xml文件，xml文件有593字节，我读下面的代码。第一个512字节为真，但其余字节为假。我读剩下的字节是00.

int fd,ret;
unsigned char *filebuffer[6400];

fd = open("filename" , O_RDONLY);
printf("file open return value : %d \n", fd);
if (fd == -1)
{
    printf("Error in openning the file!\n");
    exit(0);
}
//read the file
int i = 0;
do {
    ret = read(fd,&filebuffer[i],512);
    printf("file read return value : %d \n", ret);
    if (ret == -1)
    {
        printf("Error in reading!\n");
        exit(0);
    }
    i += ret;
    printf("i = %d, ret = %d",i,ret);

} while (ret > 0);

int k;
char tmp[6400];
memcpy(tmp,filebuffer,i);
printf("file buffer\n");
for (k = 0; k < i; ++k) {
    printf("%02x",tmp[i]);
}

close(fd);}

我正在读取文件缓冲区，我正在读取xml文件。 filebuffer示例; filebuffer：1F0583212 .....（512字节）000000

Answer 1

test = strtok (writable," ,.-"); test = strtok (NULL," ,.-"); test = strtok (NULL," ,.-"); test = strtok (NULL," ,.-"); test = strtok (NULL," ,.-"); test = strtok (NULL," ,.-");的定义不正确。将其更改为：

filebuffer
