About host file system

--- Quote Start ---

You've pasted code that has had its quotes changed.

--- Quote End ---

I've also used another example which had some quotes changed:

int main() // Load and read back filter coefficients two times

{

FILE * hostfile = fopen("/mnt/host/hello_hostfs.txt", "w");

char buffer[1024];

while (fgets(buffer, sizeof(buffer), hostfile) != null)

{

fprintf(stdout, "%s", buffer);

}

fclose(hostfile);

printf("That's all folks\n");

and I get error messages such as:

Compiling topavalon.c...

../topavalon.c:73: warning: implicit declaration of function `floor'

The only things I've changed in the code ist that I want to read data from a txt file, coz the original code was a C one. I've inserted a the hello_hostfs.txt in the project folder and have the mount name mnt/host. So what could be the problem?

Thanks
