Thread: how write the syntax for function returing a pointer to a function?

Hi ,

i know how to write a syntax for function returning a integer pointer --> int *fun(int,int)

can any one suggest to how to write a syntax for function returning a integer pointer to a function taking arguments as two integer valules.

The nice way to do it is to write out the function pointer type in a typedef, like

typedef int (*foo)(void);

Just like defining a function pointer, but foo is a name, so you can return a foo type.

Thanks laserlight and whiteflags.

Whiteflags, u mean

int *fun(void) ---> function returns integer pointer?
int (*foo)(void) --> function returning a integer pointer to a function taking no arguments?

am i right?

typedef int (*foo)(void);
foo function(int, foo);
foo bar;

bar = function(42, somefunction);


foo is a pointer to a function that returns an int and takes no arguments. bar is a variable of type foo. function is a function that takes an int argument and a foo argument, and returns a foo type.

Then I gave you a line of code calling the function named function.

Code:

Try this one,
typedef int (*foo)(void);    /* here, foo is a pointer to a function which taking no arguments and returning integer. */
foo fun();                        /* here, fun is function which takes no arguments and returing foo(pointer to a function which taking no arguments and returning integer) */
