[pdf-devel] New pdf_i64 functions using pdf_i32_t as input parameters

[Aleksander Morgado]

Another good thing to have would be, for example, a pdf_i64_div 
expecting a pdf_i32_t in the divisor or in the dividend:

pdf_status_t
pdf_i64_div_divisor_i32(pdf_i64_t *result, \
                        const pdf_i64_t dividend, \
                        const pdf_i32_t divisor);

and

pdf_status_t
pdf_i64_div_dividend_i32(pdf_i64_t *result, \
                         const pdf_i32_t dividend, \
                         const pdf_i64_t divisor);


And the same with the other pdf_i64_* functions (add, substract, and so on).




The problem I find is that with the current approach there is no real 
way of directly converting pdf_i32_t to pdf_i64_t without using a new 
variable (if treated as a blackbox). See this example where I want just 
to add '1' to a given pdf_i64_t variable:


pdf_i64_t var1;
pdf_i64_t var2;

var = pdf_i64_new(0,0);

/* here perform calculations and store value in var1 */

/* But now I need to add 1 to var1... how do I do it? */
var2 = pdf_i64_new(0,1);
pdf_i64_add(&var1, var1, var2);



It would be simpler to have something like, where there is no need to 
have another extra variable for the '1':

pdf_i64_add_i32(&var1, var1, 1);


What do you all think?
