- ---help---
- A pseudo terminal (PTY) is a software device consisting of two
- halves: a master and a slave. The slave device behaves identical to
- a physical terminal; the master device is used by a process to
- read data from and write data to the slave, thereby emulating a
- terminal. Typical programs for the master side are telnet servers
- and xterms.
-
- Linux has traditionally used the BSD-like names /dev/ptyxx for
- masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
- has a number of problems. The GNU C library glibc 2.1 and later,
- however, supports the Unix98 naming standard: in order to acquire a
- pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
- terminal is then made available to the process and the pseudo
- terminal slave can be accessed as /dev/pts/<number>. What was
- traditionally /dev/ttyp2 will then be /dev/pts/2, for example.
-
- The entries in /dev/pts/ are created on the fly by a virtual
- file system; therefore, if you say Y here you should say Y to
- "/dev/pts file system for Unix98 PTYs" as well.
-
- If you want to say Y here, you need to have the C library glibc 2.1
- or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*").
- Read the instructions in <file:Documentation/Changes> pertaining to
- pseudo terminals. It's safe to say N.

+ * Kernel tries to access the variable.
