## AI overview

An exploration of the C standard library based on P. J. Plauger's The Standard C Library. The article discusses implementation details, portability, C behavior, and the historical development of the C89 standard, with comparisons to C99 and C11 where relevant.

## Source excerpt

2019-01-19 After diving into the C language through K&R, and then studying portability (see C Portability Lessons from Weird Machines), my next challenge was to take a systematic look at the standard library. To do this I worked through P. J. Plauger's book The Standard C Library (ISBN 978-0131315099) where he examines an implementation of all the functions.
