# pdlibc - A demonstration libc that aims to be C89 compatible

---

pdlibc (Public Domain Libc) is a example implementation of the standard C library designed to be as simple as posible.

It currently provides most of the subset of functions from C89 and the linux kernels [nolibc](https://github.com/torvalds/linux/tree/master/tools/include/nolibc)

The functions that have had full tests for them (`make test`):

- abort()

- assert()

- atexit(), exit()

- atoi(), atol(), strtod()

- bsearch()

- calloc()

- cos()

- fabs()

- fopen()

- free()

- fwrite()

- getenv()

- atan() and atan2()

- setlocale(), localeconv()

- rand(), srand()

- IO buffering (setvbuf, fflush)

- labs(), abs()

- malloc()

- memcpy()

- memmove()

- memset()

- putchar()

- puts()

- qsort()

- raise()

- sin()

- Most of printf(), vfprintf(), vprintf(), and fprintf();

- sqrt()

- strcat()

- strchr(), memchr()

- strcmp(), strncmp()

- strcpy(), strncpy(), memcpy()

- strerror()

- strlen()

- The entirity of ctype.h

- The entirity of varargs.h
