teicheld / realtimeStreamFS

Project: realtimeStreamFS

Description

The program searches the biggest free square on a map with obstacles. The task required us to use exclusively the low level functions "exit, open, close, write, read, malloc and free".

Compile and run

There is a precompiled version included.

Download the software:

Linux:

wget https://github.com/teicheld/realtimeStreamFS/archive/refs/heads/master.zip && unzip master.zip && rm master.zip

Windows:

download the file using your browser: Click on "Code" and choose "Download Zip", extract it.

Installing build dependencies and build it

Linux:

cd realtimeStreamFS-master
[ ! -f /usr/bin/make ] && sudo apt install make
make

Windows:

Open the command prompt inside of the directory.
Do nothing. Use the precompiled version in the next step.

run it:

Linux:

reads from stdin:

./tests/grid_generator.perl 60 30 3 | ./realtimeStreamFS  

reads from file(s):

./tests/grid_generator.perl 30 15 3 > map1
./tests/grid_generator.perl 30 15 3 > map2 
./realtimeStreamFS map1 map2

Windows:

reads from file(s):

perl .\tests\grid_generator.perl 30 15 3 > map1
perl .\tests\grid_generator.perl 30 15 3 > map2 
.\realtimeStreamFS map1 map2

Additional tips

• grid_generator arguments:
• Run the script in a loop:

Linux:

• let the program pass a bunch of executions with increasing field-width.

  for i in {1..100}; do echo execution $i; ./tests/grid_generator.perl $i 13 3 | ./realtimeStreamFS; done

Linux:

make check
