mstrutils

Re-writing string.h for learning and fun.

What is string.h

There is no string data structure in the C programming language. There are arrays of type char. And the string.h library is a library that allows you to do some operations on these char arrays.

Why use this library?

• It does not depend standard C library
• Binary size is too small
• It has easy-readable and short code
• It distributed with BSD-3-Clause license

Currently available functions:

• mstrlen
• mstrcmp
• mstrcpy
• mstrchr
• mstrstr
• mstrncmp
• mstrncpy
• mstrcat
• mstrncat
• mmemcpy
• mmemcmp
• mmemmove
• mmemset
• mstrrchr
• mmemchr

Function headers can be seen in the mstrutils.h file.

Compiling and installing

make
make install

This command creates the libmstr.so file and copies it into ~/.local/lib/

If you can't compile or run your code with this library, check out the Troubleshooting section at the end of the README.

How to use

To use functions, you can add the text #include <mstrutils.h> to the top of your code. While compiling your code with this library, use -lmstr flag

Troubleshooting

Sometimes your system can't see ~/.local/lib/ for libraries. If you can use root, you can type

make
sudo make install PREFIX=/usr/local

But if you can't do this, add this to your .bashrc:

export LD_LIBRARY_PATH=$HOME/.local/lib:$LD_LIBRARY_PATH
export LIBRARY_PATH=$HOME/.local/lib:$LIBRARY_PATH
export C_INCLUDE_PATH=$HOME/.local/include:$C_INCLUDE_PATH

And run this command:

source ~/.bashrc
