The bits defined by
S_IRUSR,
S_IWUSR, S_IXUSR, S_IRGRP, S_IWGRP, S_IXGRP, S_IROTH,
S_IWOTH, S_IXOTH, S_ISUID, S_ISGlD and
S_ISVTX are unique. S_IRWXU is the bitwise OR of
S_IRUSR, S_IWUSR, and S_IXUSR. S_IRWXG
is the bitwise OR of S_IRGRP, S_IWGRP, and
S_IXGRP. S_IRWXO is the bitwise OR of
S_IROTH, S_IWOTH, and S_IXOTH.
Implementations may OR other implementation-dependent bits into
S_IRWXU, S_IRWXG, and S_IRWXO
,
but they will not overlap any of the other bits defined in this document. The file permission bits are defined
to be those corresponding to the bitwise inclusive OR of
S_IRWXU, S_IRWXG, and S_IRWXO.
The following macros will 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 evaluates to a non-zero value if the test is true,
0 if the test is false.
S_ISBLK(m) Test for a block special file.
S_ISCDF(m) Test for a context-dependent file
S_ISCHR(m) Test for a character special file.
S_ISDIR(m) Test for a directory.
S_ISFIFO(m) Test for a pipe or FIFO special file.
S_ISLNK(m) Test for a symbolic link.
S_ISNWK(m) Test for a network special file.
S_ISREG(m) Test for a regular file.
S_ISSOCK(m) Test for a socket.
The following are declared as functions and may also be defined as macros:
int chmod(const char *path, mode_t mode);
int lstat(const char *path, struct stat *buf);
int mkdir(const char *path, mode_t mode);
int mkfifo(const char *path, mode_t mode);
int mknod(const char *path, mode_t mode, dev_t dev);
int stat(const char *path, struct stat *buf);
mode_t umask(mode_t cmask);
Use of the macros is recommended for determining the type of a file.
WARNINGS
For 32-bit applications, st_ino will be truncated to its least significant 32-bits for file systems that use
64-bit values.
