Documentation This wiki is about working with PDCLib itself: details such as building it, porting it, design documents, policies and conventions. Note: Below documentation was written for the shepherd branch, and is retained for future reference. It is not generally applicable for the

Drawing Board For quite some time I managed to keep the number of “construction sites” in PDCLib to a minimum. Sure, there were plenty of unfinished parts (floating point, multibyte / wide characters, locales, ...), but my actual work was focussed on one part of the library only.

Policy on Extensions The documentation below refers to the shepherd branch. Design Intentions PDCLib intends to be a strict, fully conforming implementation of the runtime library component of the ISO C standard, and the portion of said library incorporated into the ISO C++ standard. It is not intended to conform to POSIX, nor the Signal Unix Specification or any other

Floating Point Explained As an extension to any internal documentation of PDCLib, and because being able to explain a subject is a good test whether I myself have understood the subject, I'll give an introduction to floating point format here. Base-10 Basics

I/O Streams The standard(s) Orientation The ISO C standard has a concept of “stream orientation”: A stream can be either wide (i.e. wchar_t) or narrow (i.e. char) oriented. A stream is created with no orientation. The first I/O to a file, or call to

Printing Floating Point Numbers To complete the printf() function of PDCLib -- which so far lacks support for %e, %f, and %g -- I needed to solve the problem of converting the binary, in-memory representation of double and long double to decimal. Using the same algorithm as for integers (divide by ten, take quotient, recurse with remainder) is not an option. Not only would repeated floating point divisions be horrendously slow: Multiplying / dividing a (base 2) floating point by 10 repeatedly …

PDCLib The Public Domain C Library Source Web-View -- Drawing Board -- Issue Tracker (GitHub) What? PDCLib is aiming at providing a fully conforming implementation of the C standard library (as defined by ISO/IEC 9899), under the licensing terms of CC0 -- "No rights reserved". PDCLib is a project predicated on the belief that some building blocks are so fundamental that they should be available freely - free of restrictions, free of license boilerplate and free of politics.

Win32 Threading Primitives This documents some of the design decisions made when implementing the C11 threading primitives on Windows tss_t Note: see C11 defect report: tss_t destruction unspecified for issues with the standard specification of tss_t. The PDCLib implementation at present follows that report.
