Hi,
A linux app that I want to build on SX using sunpro uses "struct
dirent" that has non-standard gcc extensions (ex: d_type) that are not
available in sunpro.
I wrote a test program using stat and mask mode S_IFMT as defined
sys/stat.h to get a substitute(snippet below), but the output does not
recognize symlinks. Why so?
Code snippet
-----------------------
/* Loop through directory entries. */
while ((dp = readdir(dir)) != NULL) {
/* Get file type information. */
if (stat(dp->d_name, &statbuf) == -1)
continue;
filetypeInformation = statbuf.st_mode & S_IFMT ;
printf("TYPE = %x %20s ",filetypeInformation, dp->d_name);
switch(filetypeInformation)
{
case S_IFREG : printf("Regular file. ");
break;
case S_IFDIR : printf("Directory. ");
break;
case S_IFLNK : printf("Symbolic link. ");
break;
case default : printf("I do not care about
block/chr/fifo/socket. "); break;
}
printf("\n");
}
Output
------------------
bash-3.00$ ./a.out
TYPE = 4000 . Directory.
TYPE = 4000 .. Directory.
TYPE = 8000 hi.softlink Regular file.
TYPE = 8000 a.out Regular file.
TYPE = 8000 hi Regular file.
TYPE = 8000 filetype.c Regular file.
TYPE = 8000 hi.hardlink Regular file.
TYPE = 8000 filetype2.c Regular file.
hi.hardlink and hi.softlink are links to hi, but they are shown as Regular file.
regards
Shiv
