Seems to me (from info in a later post) that M$ wsprintf uses an
internal temporary buffer that has a size of 1024 - thus resticting
the user to a buffer size of 1024,
The actual size of the user buffer cannot be determined - hence
the common 'buffer overflow' issues with sprintf.
The C standard now includes snprintf() where the application passes
in the length of the target buffer. I guess M$ might follow :-)
Some systems also have an asprintf() routine which will malloc() a
buffer that the caller must free().
