In case this helps other newbies, I moved the getstring function to a separate file containing custom functions. Also, I changed getstring's logic to go ahead and double the allocated memory each time more space is required, so that all the input can be parsed more quickly. When the entire string has been read, a final call to malloc shrinks the allocated memory so that it is just enough to hold the string--e.g., 13 bytes for "I love linux" (there's always one more byte needed than the number of characters because of the '\0' string terminator).
