Well, if this is the function prototype in your header file then it
should have a semicolon at the end...

    char *getsafe(char *buffer, int count);

It looks to me like the parse errors all go back to the missing
semicolon...of course i may be wrong but it's a good practice to fix one
error at a time as one error can cause a snowball effect....

If you're using a project file like in Rhide, you'll want to include
main.c and getsafe.c in that...other than the missing semicolon it all
looks good to me..
