[Gambas-user] unsigned int datatype for external function

[Demosthenes Koptsis]

i dont understand,

i have an external function from libc and i see size_t as datatype.

size_t is unsigned integer

on function declaration what should i set for size_t, AS Integer or AS Long?

for example i have this

'void setbuffer (FILE *stream, char *buf, size_t size)
Public Extern setbuffer(stream As Pointer, buf As Pointer, size As 
Integer) 'FIXME size_t int or long?
