Basic Unix operations, basically a subset of the POSIX specification. Using this
unit should ensure portability across most unix systems.
clocale
This unit initializes the internationalization settings in the sysutils unit with settings
obtained through the C library.
cthreads
This unit should be specified as the first or second unit in the uses clause of your
program: it will use the Posix threads implementation to enable threads in your FPC
program.
cwstring
If widestring routines are used, then this unit should be inserted as one of the
first units in the uses clause of your program: it will initialize the widestring manager
in the system unit with routines that use C library functions to handle Widestring
conversions and other widestring operations.
errors
Returns a string describing an operating system error code.
Libc
This is the interface to GLibc on a linux I386 system. It will not work for other
platforms, and is in general provided for Kylix compatibility.
ports
This implements the various port[] constructs. These are provided for compatibility
only, and it is not recommended to use them extensively. Programs using this construct
must be run as root or setuid root, and are a serious security risk on your system.
termio
Terminal control routines, which are compatible to the C library routines.
