💡 - Key Topics

File Descriptors

Understanding file descriptors is crucial for reading data in C. Each file descriptor represents an open file, socket, or other input/output resource, and it is managed by the operating system. The get_next_line function relies on the read() system call, which reads data from the specified file descriptor into a buffer. Mastery of file descriptor handling allows for efficient line-by-line reading from files and standard input.

Static Variables

Static variables maintain their value between function calls, making them essential for tracking the state of the reading process in the get_next_line function. When dealing with multiple calls to get_next_line(), a static variable can store the buffer's state across these calls, enabling the function to return subsequent lines of input. Proper use of static variables is key to implementing a robust solution without using global variables, adhering to best practices in C programming.

🛠️ - Usage

git clone https://github.com/kichkiro/get_next_line.git
cd get_next_line/

It's now possible to use the get_next_line() function by including the header files and source files.

The function prototype is char *get_next_line(int fd);
