String Size Limit

Discuss PocketC for CE (including Desktop Edition)

Hi!

Where is the limit of String size????

Sample:

string TEXT;
TEXT="Hello World!";
putsl(strlen(TEXT));

Console Shows:
11

How I define a size of string to 1024 chars????

Thx in advance.

Your example does not look right - shouldn't the length be 12 rather than 11?

To your question: I know the PalmOS version of PocketC has a limit for string constants of 255 characters. It may be that the WindowsCE version has the same. This means you cannot simply write

mystr = "sfdbaj......adssa";

with the string on the right side having more than 255 characters. But this only concerns string constants that you assign to a string. Strings themselves can be any length up to the available storage space of your device (at least I haven't yet hit any limit even with very long strings, and I know string storage space allocation is done dynamically). And for the string constant problem, there is an easy workaround: concatenate several smaller strings when you assing them to the variable:

mystr = "first chunk" + "second chunk" + .... + "nth chunk";

where each chunk can be up to 255 characters.

It should be 13 if the string is NULL terminated string.
Maybe PocketC is different.

PocketC had no problem storing a whole HTML file into one string.
(I wrote HTML2TXT tool)

I think that string lengths are limited only by the amount of available memory.

Look at ustring.h from the example extension dll kit.
