Writing a dynamic library in Crystal, and calling it from C

• Download all files.
• Build the Crystal part:

crystal build --release --cross-compile --prelude ./no_main library.cr
              ^ You can leave this out
                        ^ We want to link ourselves!
 ^ Use our custom prelude!

# script created for reading SMS messages from 3G modem connected to PC
# 1) it looks for modem
# 2) reads all SMS messages from modem
# 3) prints all found SMS messages to stdout only if total messages count
#    greater than SMS_STORE_COUNT (default is 3)
# 4) save all but SMS_STORE_COUNT messages to txt files and
#    delete them from modem
