C: How do I define a pointer to a function which returns a char pointer?


How do I define a pointer to a function which returns a char pointer?


char * ( *p )( ) ; 

or

typedef char * ( * ptrtofun )( ) ;   
ptrtofun p ;

Here is a sample program which uses this definition.

main( )   
{   
  typedef char * ( * ptrtofun ) ( ) ;   
  char * fun( ) ;   
  ptrtofun fptr ;   
  char *cptr ;   
  fptr = fun ;   
  cptr = (*fptr) ( ) ;   
  printf ( "\nReturned string is \"%s\"", cptr ) ;   
}   
char * fun( )   
{   
  static char s[ ] = "Hello!" ;   
  printf ( "\n%s", s ) ;   
  return s ;   
}
