Currently I have som开发者_C百科e code like (condensed and removed a bunch of error checking):
dp = readdir(dir);
if (dp->d_type == DT_DIR) {
}
This works swimmingly on my Linux machine. However on another machine (looks like SunOS, sparc):
SunOS HOST 5.10 Generic_127127-11 sun4u sparc SUNW,Ultra-5_10
I get the following error at compile time:
error: structure has no member named `d_type'
error: `DT_DIR' undeclared (first use in this function)
I thought the dirent.h
header was crossplatform (for POSIX machines). Any suggestions.
Ref http://www.nexenta.org/os/Porting_Codefixes:
The struct dirent definition in solaris does not contain the
d_type
field. You would need to make the changes as follows
if (de->d_type == DT_DIR)
{
return 0;
}
changes to
struct stat s; /*include sys/stat.h if necessary */
..
..
stat(de->d_name, &s);
if (s.st_mode & S_IFDIR)
{
return 0;
}
Since stat
is also POSIX standard it should be more cross-platform. But you may want to use if ((s.st_mode & S_IFMT) == S_IFDIR)
to follow the standard.
