You first must sign up for Twilio at twilio.com. You will have to provide a cell phone number. You will have a trial account, however Twilio has gifted the class a promotion code that provides $20 in credit. Without the code you have 30 days to use your account. After upgrade the $20 will be used for a $1/month charge and a per message charge.
You can immediately test the account with your phone, to see if it works.
Then please read the API information:
https://www.twilio.com/docs/api/rest https://www.twilio.com/docs/api/rest/messageI have provided two entry places. You can read background on REST on wiki, and let's read the original paper by Fielding and here is a tutorial that might help ease in the reading:

Once you have an account, with a SID and an Authorization string (like you password) you can try the API Explorer (Twilio login required):
https://www.twilio.com/user/account/messaging/dev-tools/api-explorer/message?expanded=0You can then experiment with command line Twilio using the standard unix tool "curl", see class/proj5/makefile.twilio, after adapting to your account SID, TOK, Twilio number, and a target number (which you might have to register using your Twilio Dashboard).
Curl is also a library, that can be called from inside a C program. See the test program in class/https.c and the Makefile target, and the resources:
https://curl.haxx.se/libcurl/c/libcurl-tutorial.html https://curl.haxx.se/libcurl/c/https.html (this program is in the class directory) https://github.com/laurentluce/twilio-cplusplus/blob/master/Rest.cpp (this program is in C++, and Twilio referenced it)
The class/proj5 has sample code for a GNU regex library and a Base64 encoder/decoder. References:
http://www.gnu.org/software/libc/manual/html_node/Regular-Expressions.html#Regular-Expressions https://gist.github.com/barrysteyn/7308212It might be useful to use these libraries.
Deliver either a C code and subroutines.
The actions should include at least:
