a short test.

how do i allocate memory for doubles and float and then read it as numbers?

OK i found out. sorry.

object result = 0 
atom width = allocate(8), height = allocate(8) 
atom docHandle 
 
c_proc(FPDF_InitLibrary) 
constant book = allocate_string("3658071664.pdf") 
docHandle = c_func(FPDF_LoadDocument, {book, 0}) 
delete(book) 
integer j = c_func(FPDF_GetPageCount, {docHandle}) 
integer i = c_func(FPDF_GetPageSizeByIndex, {docHandle, 100, width, height}) 
c_proc(FPDF_CloseDocument,{docHandle}) 
c_proc(FPDF_DestroyLibrary) 
 
 
?j 
?i 
object result = 0 
atom width = allocate(8) 
atom height = allocate(8) 
atom docHandle 
 
c_proc(FPDF_InitLibrary) 
constant book = mem:allocate_string("3658071664.pdf") 
docHandle = c_func(FPDF_LoadDocument, {book, 0}) 
delete(book) 
integer j = c_func(FPDF_GetPageCount, {docHandle}) 
integer i = c_func(FPDF_GetPageSizeByIndex, {docHandle, 100, width, height}) 
c_proc(FPDF_CloseDocument,{docHandle}) 
c_proc(FPDF_DestroyLibrary) 
 
 
?j 
?i 
?float64_to_atom(peek({width, 8})) 
?float64_to_atom(peek({height, 8})) 
delete(width) delete(height)  
wait_key()
