My very first own library regrouping some usual functions in C
This project aims to code a C library regrouping usual functions that you’ll be allowed to use in all your other projects.
Project is created with:
- C
This project was divided into three parts and I added a new one for extra functions that I will formulate on my own as I advance in the 42SP course.
In this part, I had to re-code some libc functions as defined in their man
| Name | Description |
|---|---|
| memset | set memory areas to specific value |
| b_zero | write zero-valued bytes |
| memcpy | copy memory areas |
| memccpy | copy memory area until character found |
| memmove | copy memory areas, accept overlap |
| memchr | scan memory for a character |
| memcmp | compare memory areas |
| Name | Description |
|---|---|
| strlen | calculate len of string |
| strlcpy | size-bounded string copy |
| strlcat | size-bounded string concatenation |
| strchr | scan string for a character |
| strrchr | scan string for last occurance of a character |
| strnstr | locate a substring |
| strncmp | size-bounded comparation of two strings |
| atoi | convert a string to integer |
| Name | Description |
|---|---|
| isalpha | classification routine: alphabetic character |
| isdigit | classification routine: number character |
| isalnum | classification routine: alphanumeric character |
| isascii | classification routine: ASCII character |
| isprint | classification routine: printable character |
| toupper | convert letter to uppercase |
| tolower | convert letter to lowercase |
| Name | Description |
|---|---|
| calloc | allocate and free dynamic memory |
| strdup | duplicate a string |
In this part, I had to code some functions that are either not included in the libc or included in a different form
| Name | Description |
|---|---|
| substr | create new string with the substring of a string |
| strjoin | concatenate two string into a new one |
| strtrim | create new string with a set of characters removed from beginning and end |
| split | split string into an array of strings |
| itoa | convert integer to string |
| strmapi | create new string from application of function to each character of a string |
| Name | Description |
|---|---|
| putchar_fd | output a character to the given file descriptor |
| putstr_fd | output a string to the given file descriptor |
| putendl_fd | output a character to the given file descriptor, followed by a newline |
| putnbr_fd | output an integer to the given file descriptor |
In this part, I had to code some important functions for the manipulation of linked lists.
| Name | Description |
|---|---|
| lstnew | create new list |
| lstadd_front | add new element to the beginning of list |
| lstsize | count the elements of a list |
| lstlast | finds the last element of list |
| lstadd_back | add new element to the end of list |
| lstdelone | delete a specific element of list |
| lstclear | delete sequence of element of list |
| lstiter | iterates the list and applies the function to the content of each element |
| lstmap | apply function to content of all list's elements into new list |
In construction...
Besides the function's files, this repository contains a libft.h file and a Makefile so that you can compile all the functions and use them in your project. To generate a libft.a file one of the commands bellow:
// Part 1 and Part 2 functions only
make
// all functions included
make bonus
and then compile your project with this file added to your compile command, such as:
gcc ~/path/to/your/project ~/path/to/your/libft.a
to keep your folder clean you may use one of the commands bellow:
// remove only the .o files
clean
// remove the .o files and the .a file
fclean
