Did anyone mention that a directory must have the x flag for a user to search (ls) it? Or what about the -R flag, which recursively gives subdirectories the same permissions?
And, you people are only thinking
user-
level. It's also a
system call:
#include <sys/types.h>
#include <sys/stat.h>
int chmod( const char *path, mode_t mode );
int fchmod( int fd, mode_t mode );
fchmod does a
chmod on an open
file descriptor. Here are the
flags for "
mode", done with an
or,
as usual:
S_ISUID setuid
S_ISGID setgid
S_ISVTX sticky bit
S_IRUSR owner read
S_IWUSR owner write
S_IXUSR owner execute/search
S_IRGRP group read
S_IWGRP group write
S_IXGRP group execute/search
S_IROTH other read
S_IWOTH other write
S_IXOTH other execute/search
