Minimal libc implementation, heavely copied/inspired by PDCLIB. When I need a function that is a reimplementation of libc I put it here, together with its unittests. Most if not all functions contain a few unittests, look in the directory test for those.
use git clone --recurse-submodules https://github.com/Squantor/$(PROJECT).git to clone the repo and its submodules.
This project uses gnu make as its build system on a Linux platform. There are two build targets: release and debug. Release builds with optimizations and minimal debugging information. Debug builds with no optimization and full debug information.
$ make debug
$ make release
This program depends on my slightly modified version of minimal C testing framework. This is automatically checked out when using git clone --recurse-submodules.
- ctype: isalnum, isalpha, isascii, isblank, iscntrl, isdigit, isgraph, islower, isprint, ispunct, isspace, isupper, isxdigit, tolower toupper
- errno: errno variable
- stdlib: strstol, strto, strtol, stroul
- string: memchr, memcmp, memcpy, memmove, memset, strcat, strchr, strcpy, strlen, strncmp, strncpy, strnlen, strpbrk, strrchr, strspn, strstr, strto, strtok
- add printf
This is only a partial C standard library implementation and tries to conform to the standard. Basically, when I need a libc function, I add it here.
