[Mono-devel-list] Problem with P/Invoke

[Carlos Alberto Cortez Guevara]

Hi,

I was playing with some P/Invoke samples, and I found that the next code
doesn't work perfect.

I'm loading the strncpy function from the standard library (libc), and
the first call works perfect. However, in the second call (and third,
..) it doesn't work.

Is this a bug?

Regards,
Carlos.
