[newbie]:function returns a pointer to a string

[uy do]

Hi,
I see a function but I dont white understand a few things. So please help me
to clear it out.
The code is as follow
-------------
//global variable
char buf[32768];

char * myfunc(s1)
char *s1;
{
//definition of the function
return (buf);
}

Greetings.

char * myfunc(s1)
char *s1;
{
//definition of the function
return (buf);
}

This is old-style (K&R) C, which predates the ANSI/ISO standards. Nowadays
the equivalent syntax you suggested is preferred, and all modern compilers
support it.

This question is also answered in the FAQ.

It's an old K&R style definition. It's more or less the same. Not
exactly the same though - the way it handles argument promotions
differs. I don't remember exactly how it differs. K&R style definitions
are still valid in standard C, but deprecated. <OT>C++ does not allow
K&R style definitions.</OT>

char * myfunc(s1)
char *s1;

My questions is why don't they define the function as simple as char
*myfunc(char *s1) ?

It's just an old-style function definition.
