Data Structures
struct	stat
	The <sys/stat.h> header shall define the stat structure. More...

Macros
#define	FILETYPE_BITS   3
	Number of bits needed to store a FileType. More...
#define	FILETYPE_MASK   7
	Masker value for all FileTypes. More...
#define	FILEMODE_BITS   9
	Number of bits required for all FileModes. More...
#define	FILEMODE_MASK   0777
	Masker value for all FileMode values. More...
File stat type bits.
The <sys/stat.h> header shall define the following symbolic constants for the file types encoded in type mode_t. The values shall be suitable for use in #if preprocessing directives.
#define	S_IFMT   (FILETYPE_MASK << FILEMODE_BITS)
	Type of file. More...
#define	S_IFBLK   (FileSystem::BlockDeviceFile << FILEMODE_BITS)
	Block special. More...
#define	S_IFCHR   (FileSystem::CharacterDeviceFile << FILEMODE_BITS)
	Character special. More...
#define	S_IFIFO   (FileSystem::FIFOFile << FILEMODE_BITS)
	FIFO special. More...
#define	S_IFREG   (FileSystem::RegularFile << FILEMODE_BITS)
	Regular. More...
#define	S_IFDIR   (FileSystem::DirectoryFile << FILEMODE_BITS)
	Directory. More...
#define	S_IFLNK   (FileSystem::SymlinkFile << FILEMODE_BITS)
	Symbolic link. More...
#define	S_IFSOCK   (FileSystem::SocketFile << FILEMODE_BITS)
	Socket. More...
#define	S_IRWXU   FileSystem::OwnerRWX
	File mode bits. More...
#define	S_IRUSR   FileSystem::OwnerR
	Read permission, owner. More...
#define	S_IWUSR   FileSystem::OwnerW
	Write permission, owner. More...

	Read, write, execute/search by group. More...
#define	S_IRGRP   FileSystem::GroupR
	Read permission, group. More...
#define	S_IWGRP   FileSystem::GroupW
	Write permission, group. More...
#define	S_IXGRP   FileSystem::GroupX

#define	S_IXOTH   FileSystem::OtherX
	Execute/search permission, others. More...
File type macros.
The following macros shall be provided to test whether a file is of the specified type. The value m supplied to the macros is the value of st_mode from a stat structure. The macro shall evaluate to a non-zero value if the test is true; 0 if the test is false.
#define	S_ISTYPE(mode, mask)   (((mode) & S_IFMT) == (mask))
	Test for mode bits. More...
#define	S_ISBLK(m)   S_ISTYPE(m, S_IFBLK)
	Test for a block special file. More...
#define	S_ISCHR(m)   S_ISTYPE(m, S_IFCHR)
	Test for a character special file. More...
#define	S_ISDIR(m)   S_ISTYPE(m, S_IFDIR)
	Test for a directory. More...
#define	S_ISFIFO(m)   S_ISTYPE(m, S_IFIFO)
	Test for a pipe or FIFO special file. More...
#define	S_ISREG(m)   S_ISTYPE(m, S_IFREG)
	Test for a regular file. More...
#define	S_ISLNK(m)   S_ISTYPE(m, S_IFLNK)
	Test for a symbolic link. More...
#define	S_ISSOCK(m)   S_ISTYPE(m, S_IFSOCK)
