Question: How do I define a pointer to a function which returns a char pointer?
Answer: 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 ; } |
