I extended dirent.c with the methods telldir() and seekdir(). A patch
is attached. My implementation is very simple, i'm not sure that it is
completely correct but for a simple example i compiled for Cygwin/x86
and Cygwin/ARM it gives the same results.
The Arm version has been tested on a Pocket PC Emulator
The example is :
--- start telldir.c ---
#include <dirent.h>
#include <sys/types.h>
#include <errno.h>
#include <string.h>
#include <stdio.h>
int main(){
DIR *dir = opendir(".");
if (dir == NULL)
{
printf("Err: %s\n", strerror(errno)) ;
}
else
{
long int currLoc;
struct dirent *dirEntry;
int i = 0;
for (i = 0; i < 7; i++) {
currLoc= telldir(dir);
printf("Seekdir to %d \n", currLoc);
seekdir(dir, currLoc);
dirEntry = readdir(dir);
printf("Readdir: %s\n", dirEntry->d_name);
}
}
}
-- end telldir.c --
i created a directory called telldir, and into it i created the dir
"a,b,c,d,e,f"
on both Cygwin/X86 and Cygwin/ARM (windows mobile) the output is:
--- start output ---
[EMAIL PROTECTED] /cygdrive/c/Code/telldir
$ ./telldir-x86.exe
Seekdir to 0
Readdir: .
Seekdir to 1
Readdir: ..
Seekdir to 2
Readdir: a
Seekdir to 3
Readdir: b
Seekdir to 4
Readdir: c
Seekdir to 5
Readdir: d
Seekdir to 6
Readdir: e
--- end output ---
i'm neither an expert in systems programming nor in CeGCC, i tried to
follow the style of the other functions in dirent.c . Feel free to
comment on the code, it can be certainly improved :)
