Pointr to function

[Rafal 'Raf256' Maj]

Hi,
how can I make variable 'ptr' - an pointer to function taking parameter
'int' and returning 'float' ?

How can I define 'tPtr' to by type as above?

typedef float function_t(int);
float f(int);
function_t ptr = f;

typedef float function_t(int);

Wrong, the typedef above does not establish any kind of pointer.

typedef float (function_t*)(int);

You mean:

typedef float (*function_t)( int );

Thanks for the correction.
