[pdf-devel] Assigning a 64-bit value to pdf_i64_t

[Aleksander Morgado]

Hi,

We have a function that can be used to initialize a pdf_i64_t with a 
pdf_i32_t:

void
pdf_i64_assign_quick (pdf_i64_t *bignum,
                      const pdf_i32_t value,
                      pdf_status_t *p_status);

But, what if I am in a OS with built-in 64-bit support (like I guess we 
all are) and I want to assign a 64-bit value (coming from system 
functions for example) into a pdf_i64_t?

Well, we can also use `pdf_i64_assign_quick' for that, as in those types 
of OS that function will just be a macro, which doesn't take care of 
type sizes. Note that we can't use "=" for that, as it would break our 
built-in 64-bit support.

But, I don't think it's clear from the API document point of view, as it 
seems that only 32-bit integers are allowed. How can we explain this in 
the document? Just with a note saying... "hey, you can also use a 64-bit 
value in this function instead of a pdf_i32_t"... or what?

And BTW, didn't we talk about adding an option to configure in order to 
force the use of our built-in 64-bit support?

Cheers,
-Aleksander
