The get_next_line project is part of the 42 school curriculum, challenging students to implement a function that reads a line from a file descriptor. This project aims to improve file reading skills in C and understand dynamic memory allocation.
The get_next_line function reads a line from a given file descriptor, such as a file or standard input, and stores it in a buffer. Key features include:
- Reading a line: Reads a line from the file descriptor until a newline character (
\n) is encountered or the end of the file is reached. - Dynamic memory allocation: Allocates memory as needed to store the line, enabling efficient handling of lines of varying lengths.
- Handling multiple file descriptors: Supports reading from multiple file descriptors without losing track of their respective positions.
- Clone the project:
git clone https://github.com/seungwonme/get_next_line- Navigate to the project directory:
cd get_next_line && rm -rf .git- Link the library in your project and include the header file:
#include "get_next_line.h"
int main(void)
{
int fd;
char *line;
fd = open("example.txt", O_RDONLY);
while (get_next_line(fd, &line))
{
ft_printf("%s\n", line);
free(line);
}
close(fd);
return (0);
}- To clean up object files:
make clean- To delete all build files:
make fclean- To clean and rebuild the library:
make rechar *get_next_line(int fd);
