The GCC/GDB/Make workshop at Rajabazar Science College organized by Calcutta University and Indian GNU/Linux User Group Calcutta has come to an end.

Today at around 02:15 hours I learnt to use GNU Readline in C programs. No particular reason for me to do so, except that the recent changes in build infrastructure of GNU Parted initiated by Jim Meyering had suddenly caused the 'configure' script from detecting my system's Readline libraries. After my sleep-deprived eyes had failed to detect any particular bug in configure.ac, I landed up at the GNU Readline manual.

I must say I have not yet solved the Parted problem, but managed to scrible an elementary program with ample help from the manual. Find it here.

Dependencies:a. readlineb. readline-develc. termcapd. libtermcape. libtermcap-devel

Compilation instructions:$ gcc readline1.c -lreadline -ltermcap

Here is a nice way to mark a particular C function as deprecated. It might come in handy if you are in the process of developing an API or library and intend to phase out a particular component of it. The Linux kernel developers also use this method.

Here is what you get on compiling and running it:
[rishi@Sunflower devel]$ gcc -ansi -pedantic foo.c -o foo
foo.c: In function ‘main’:
foo.c:8: warning: ‘foo’ is deprecated (declared at foo.c:5)
[rishi@Sunflower devel]$ ./foo
I am foo.
[rishi@Sunflower devel]$
