Simply gcc compilation error using sys/dir.h

[Paolini]

compiling this using
gcc -o xxx xxx.c

I obtain this error message in function Main
6 storage size of 'ff' isn't known

Can any help me ?


#include <stdio.h>
#include <sys/dir.h>

int main (int argc, char* argv[])
{
struct ffblk ff;
int rc;
rc = findfirst ("*.*", &ff, ~0);
while (rc)
{
printf ("%s\n", ff.fa_name);
rc = findnext (&ff);
}
return 0;
}

Not here.

#include <stdio.h>

Non standard

#include <sys/dir.h>

Non standard.

int main (int argc, char* argv[])
{
struct ffblk ff;

What is ffblk?

Please, I suspect <sys/dir.h> being an implementation specific
header. Ask in the newgroup supporting that implementation.

According to D.5 it is standard (but deprecated).

Excuse me, i'm using Gcc where can i find correct 'standard'
libraries? name and structures documentation?
To read directory tree and make a directory whot is the correct
library to use (under Linux using gcc)?

Thank's

That's off-topic in this group, try a gnu group.

But not-quite-offtopic, also take a look at <url:http//www.boost.org>. Reason
it's not quite offtopic: much of it will probably end up in the next standard.
