displaypcx need  a char ** argument, tausta[1] is a char.
The correct call should be: displaypcx(1,&tausta) (because tausta is a
char*, so &tausta is a char**)
Anyway it will not work, because when the original program is called,
argv[0] is the name of the program ("displaypcx") and argv[1] is the
first argument. Your string is located at &(tausta)[0]. So the function
will search for &(tausta)[1], and segfault. The best thing to do is to
modify the displaypcx function to your needs :)
