libft

This is a C library that provides a set of basic functions that can be used in C programming.

Getting Started

To use the library, include the libft.h header file in your project and link to the libft.a file during compilation.

Function List

The following functions are provided by the library:

Character Testing

int ft_isalpha(int n): tests for an alphabetic character. int ft_isdigit(int n): tests for a digit. int ft_isalnum(int n): tests for an alphanumeric character. int ft_isascii(int n): tests for an ASCII character. int ft_isprint(int n): tests for a printing character.

String Processing

size_t ft_strlen(const char *str): returns the length of a string.

void *ft_memset(void *buf, int c, size_t len): fills a block of memory with a given value.

void ft_bzero(void *string, size_t byte_length): write zeroes to a string

void *ft_memcpy(void *dest, const void *source, size_t bit_size): copies memory from one location to another.

void *ft_memmove(void *dest, const void *src, size_t len): copies bytes from memory area src to memory area dest

size_t ft_strlcpy(char *dest, const char *source, size_t length): copy and concatenates

size_t ft_strlcat(char *dst, const char *src, size_t dstsize): copy and concatenates

int ft_toupper(int c): converts a lower-case letter to upper-case.

int ft_tolower(int c): converts an upper-case letter to lower-case.

char *ft_strchr(char *s, int c): locate character in a string

char *ft_strrchr(const char *source, int c): locate last occurrence of a character

int ft_strncmp(const char *source1, const char *source2, size_t n): compare at most n characters from two strings

void *ft_memchr(const void *source, int c, size_t n): search for a byte in an area of memory

int ft_memcmp(const void *source1, const void *source2, size_t n): compare byte sequences

char *ft_strnstr(const char *haystack, const char *needle, size_t len): Locate a substring

int ft_atoi(const char *number): convert a string to an integer.
