[Gambas-user] [SegFault 11] Enumerating HttpClient.Headers with For Each

[roberto]

to bypass the segfault 11 , if I wanted to use the external library 
libgmime with:

Library "libgmime-2.6:0"

the declaration of the function should be this:

Private Extern g_mime_part_get_content_object(GMimePart As Pointer) As 
Pointer

and  my data is in variable hPart as MimePart

how i can pass hPart to the libgmime function?

Regards


how do I go hpart to function?
