Reimplementing GNU C Library & Linux SysCmd + Shell

About the Project

In this project, the standard library was recreated from scratch as well as system commands and a SHELL in order to execute them.

Developped with :

• C (only system Call)

Getting Started

The project has a makefile in order to compile the library, the Test file, the SHELL file and the different system commands.

the library contains 4 files :

• mini_string.c

  • mini_printf
  • mini_scanf
  • mini_exit_string
  • mini_strlen
  • mini_strcpy
  • mini_strcmp
  • mini_strncmp
  • stringToInt (ATOI)
  • intToString (ITOA)
  • mini_perror

• mini_memory.c

  • mini_calloc
  • mini_free
  • mini_exit

• mini_io.c

  • mini_fopen
  • mini_fread
  • mini_fwrite
  • mini_fflush
  • mini_fclose
  • mini_exit_io
  • mini_fgetc
  • mini_fputc

• mini_lib.h
