Unix and UNIX are both POSIX willing operative systems. POSIX defined a accepted programme to the low-level operative system which greatly reduces the amount of work required to display UNIX and UNIX software.

Unix and UNIX code development

The accepted individual command distinction and scripting programme was based on the Korn shell. Other user-level programs, services and utilities include awk, echo, ed, and hundreds of others. Required program-level services include basic I/O (file, terminal, and network) services. POSIX also defines a accepted threading library API which is supported by most modern operative systems.

Currently POSIX documentation is divided in three parts:

POSIX Kernel APIs

POSIX Commands and Utilities

POSIX Conformance Testing

Linux Development requires both POSIX and 3rd party/native GDI and GUI frameworks to create usable UNIX and UNIX software. DOTNUTSHELL crapper create highly ascendible and usable POSIX code which crapper be separate on UNIX and Linux. The code crapper range from simple utilities to distributed code which has to be separate on heterogenous platforms much as Linux, UNIX and Windows.

Linux and UNIX development is also the desired papers and support for the creation of embedded software:

Embedded code and embedded systems, are those that require 100% of resources shared across a single papers often used to monitor, update and curb hardware.

DOTNUTSHELL has experience in creating robust, efficient embedded code running as a monolithic Operating system, or a Kernel add-on in an Embedded UNIX distribution.

It is the responsibility of the underlying embedded code system to reassert land information, persist changes to element configuration as well as gaurantee transaction and concurrency curb at the element interface-level.

We have experience in creating:

MontaVista based embedded software

Embeddix based embedded software

Linux Driver creation

low-level element and bus programme strategies and mechanisms

I/O mapping and application/kernel expanse mixing

Real-time application development

Cross papers development

Assembler/C/C++ based embedded code development

POSIX development
