Function Declaration question
PostPosted: Wed Jul 02, 2003 1:18 pm     Reply with quote

PCH appears to require any referenced function to be created before it's first call. For example...


int test1(void)
{
...
}

void main()
{
....
x = test1();
....
}

compiles but


void main()
{
int test1(void);
....
x = test1();
....
}


int test1(void)
{
...
}


results in an "Undefined identifier test1" error.

DOes anyone know if PICC demands functions to be created in such an order as to require creation before it's first call?

You have to put the function prototype above main().
Example:


int test1(void);


void main()
{
....
x = test1();
....
}


int test1(void)
{
...
}


:=
:=void main()
:={
:=int test1(void);
:=....
:=x = test1();
:=....
:=}
:=
:=
:=int test1(void)
:={
:=...
:=}
:=

just use c functions prototipes!

ie:

int test1(void);

void main() { x = test1(); .... }

int test1(void) { ... }
