Challenge
Read a file line by line from a file descriptor, without knowing the size of the lines or of the file in advance, while managing a buffer and the memory kept from one call to the next.

Get Next Line: reading lines from a file descriptor in C
École 42 project: a C function that reads a line from a file descriptor across successive reads, preserving state between calls through a static variable.

Impact
- Reading a file line by line regardless of the line size
- State preserved between calls through a static variable
- Handling of the buffer, end of file and multiple descriptors
What was done
A function that reads in blocks (read) and keeps its state between the
calls through a static variable to reconstruct each line, handling the
buffer, the end of file and several descriptors at the same time.
Stack
The technologies used on this mission.
