The 42 get next line
project is a programming exercise that involves writing a function in the C programming language that reads a line from a file descriptor. The goal of the project is to create a function that reads a line from a file descriptor, including the newline character at the end of the line, and stores the result in a buffer.
- The function takes as input a
file descriptor
and abuffer
to store the line. - The function reads one character at a time from the
file descriptor
and stores it in thebuffer
. - If the character is a
newline
, the function stops reading and stores the newline character in thebuffer
. - If the character is not a
newline
, the function continues reading until it reaches the end of the line or the end of the file. - The function returns the number of characters that were read and stored in the
buffer
, including thenewline
character.
There are a few additional requirements and constraints that are often part of the "42 get next line" project. For example, the function may be required to handle multiple file descriptors simultaneously, to handle errors and edge cases, and to use a certain number of bytes of memory.
