Re: [avr-gcc-list] passing pointers to functions

[John Myers]

It may be because ptr2func is not declared before the prototype. Try putting the typedef of ptr2func in the header file above the prototypes.

I have been having difficulty passing a function pointer in a function call.  In
researching the issue, it appears that there is a compiler issue with doing that &
I've tried a couple of suggested fixes with no luck.

Since the version appears to required in order to get the correct fix, my version
is gcc-4.3.0.

This is my last attempt.

1.  Here is the function prototype in the .h file

void InsertTask(ptr2func TaskPtr);                      // line 42 in atm328.h

2.  Here is the code in the single .c file containing all the code related to this
issue.

typedef void (*ptr2func)(void);

Here is the function

void InsertTask(ptr2func TaskPtr)

Here is the call

       InsertTask(LEDTask);


3. Here is the returned error.

../atm328.h:42: error: expected ')' before 'TaskPtr'


Before I try updating avr gcc, is there something else that I need to do in order
to make this work?

thanks.
