ILocale->FormatString32() example

I'm searching for an example of ILocale->FormatString32() showing how to write custom PutCharFunc. I'm particularly interested in a PutCharFunc just counting characters.

Well, I've found that I can use IUtility->VSNPrintf() for both counting characters and do formatting to a buffer. I guess that locale.library "takes over" the VSNPrintf() when installed, so the result is exactly the same. Still an example showing non-standard PutChProc for FormatString32() may be interesting, as the autodoc is not clear (for example it specifies the third parameter as "TEXT", whatever it means...).

@krashan

TEXT is the base type for STRPTR and CONST_STRPTR. So basically it is equal to "char", which matches the Autodoc:

Quote:

This means the third parameter is just a single character and NOT a pointer to a NUL terminated string.

@krashan

Here are examples for various format functions:

It's for OS 3.x, though, i.e. FormatString32 is not contained. But it should be similar to the older FormatString.

Also be aware that SNPrintf and its kin return a count that includes the terminating null, so you get a return value one more than you would expect from the C library printf() or sprintf().
