Header file compilation error...

Hi,

I have a main.c file which uses my functions printhello() and printbye(). The definition (prototype) of these functions is in printroutines.h and they are implemented in printroutines.c. They are:

printroutines.h
===============
void printhello(char *user);
boolean printbye(char *byestring);

printroutines.c
===============
void printhello(char *user)
{
   printf("Hell %s\n", user);
}

boolean printbye(char *byestring)
{
   printf("Are you sure you want to %s?\n", byestring);
   ....
   return <boolean variable>;
}

main.c
======

main()
{
   ...
   ...
   printhello(username);
   ...
   ...
   printbye("quit");
}
I am compiling on Unix with the CC compiler and I get the following compilation error:


cc -c main.c -I. -I/usr/include -g -D__USE_BSD -O2 -threads -funroll-loops -DUSE_XSHM
cc: Info: File not optimized; use -g3 if both optimization and debug wanted. (suppressoptlvl)
cc: Error: printroutines.h, line 11: Missing ";". (nosemi)
boolean printbye(char *byestring);
--------^
*** Exit 1
Stop.                                                                          

Why am I getting this problem with the prototype of printbye??

Thanks in advance!

Corrections..

the printhello routine should've printed...

   printf("Hello...
instead of
   printf("Hell....
:-)

I am also including the printroutines.h in main.c.

Thanks.

I guess the 'boolean' type is not defined, this usually leads to this error. As 'boolean' is no standard ANSI C type, you'll have to create it on your own:

typedef int boolean;
printroutines.h
===============

typedef int boolean;

void printhello(char *user);
boolean printbye(char *byestring);

In addition to what jkr has added,
  you are returning a boolean value from the function printbye ,hence, in main.c the line
  printbye("quit");
should be written as
  retval=printbye("quit");
where retval is defined of the typedef boolean in main.c itself.

Neelima, why did you post that as an 'answer'? You're not even addressing the problem in your posting... Please take the time and scroll down to the bottom of this page to read the 'Tips on Comments and Answers'.

Define your data type as 'bool' not 'boolean';
