Writing a function pointer in c

Question

I was recently reading a code, and found that a function pointer is written as :

int (*fn_pointer ( this_args ))( this_args )

I usually enc

Answer 1

From cdecl (which is a handy helper tool to decipher C declarations):

int (*fn_pointer ( this_args1 ))( this_args2 )

declare fn_pointer as function (this_args1) returning pointer to function (this_args2) returning int

Hence the former is a function, that returns pointer to function, while the latter:

return_type (*fn_pointer ) (arguments);

is an ordinary "pointer to function".
