FINAL GRADE: 125/100
A function that reads a line from a file descriptor and returns it, allowing line-by-line reading of a text file. The buffer size can be varied during compilation.
| Function name | get_next_line |
|---|---|
| Prototype | char *get_next_line(int fd); |
| Turn in files | get_next_line.c, get_next_line_utils.c, get_next_line.h |
| Parameters | fd: The file descriptor to read from |
| Return value | Read line: correct behavior NULL: there is nothing else to read, or an error occurred |
| External functs. | read, malloc, free |
| Libft authorized | No |
| Description | Write a function that returns a line read from a file descriptor |
To compile the program with main.c and read from a text file with a custom buffer size, use the following command:
gcc -Wall -Werror -Wextra -D BUFFER_SIZE=42 get_next_line.c get_next_line_utils.c get_next_line.h main.c -o gnl
To read from standard input, compile the program and run it. Then, type your text in the console and interrupt the input stream with Ctrl+D (EOF).
To redirect input from one file to another, execute:
./gnl < text.txt > output.txt
There are two versions of the get_next_line() function.
- The mandatory version, which requires a file descriptor as a parameter.
- The bonus version, which allows the management of multiple file descriptors simultaneously.
The project has been tested with the following testers:
