Re: DateDiff question

For this to work on Linux, you need to replace the swprintf function

Format.pb

Protected Buff.s
Buff = Format( "%i.%02i.%02i %02i:%02i:%02i", @R(0), @R(1), @R(2), @R(3), @R(4), @R(5))

Re: Format string with some values like sprintf (C) - Update

... From what I've read online when it comes to C, float arguments to variadic function are promoted to double. So for a function like sprintf / swprintf, you always need to use a double when importing the function or using PrototypeC.
After that, passing a float (.f) works fine as PB will convert ...

Re: Format string with some values like sprintf (C) - Update

... data as a float ?
FISTP stores the float as an integer which won't work.
But there also seems to be a bug on PureBasic Windows x64.

I can't get swprintf to work cross platform so here's an example with sprintf instead. ImportC ""
sprintf(*str, format.p-ascii, arg1.d=0, arg2.d=0)
EndImport

Re: Format string with some values like sprintf (C) - Update


Probably the x64 calling convention.


But it does the same on x86


ImportC ""
swprintf(*str.string,format.s,*args1=0,*args2=0)
EndImport

Global str.s{128}
Global i = 12
Global f.f = 3.14

What's wrong with floats? :?:

Define.s r$ = StrD(#PI,4) + "ZZZ"
