I have two GU_Detail(geo1, geo2) and I want copy/move point attributes from geo1 to primitive attributes in geo2(if they dont exist).
I dont care about values, I am just want to copy names and types of attributes.
Cannot find any example for this

You should be able to do something like this:
const GA_Attribute *source_attr;
const GA_AttributeDict *dict;
GA_AttributeDict::iterator a_it;
GA_RWAttributeRef dest_gah;
dict = &geo1->pointAttribs();
for (a_it=dict->begin(GA_SCOPE_PUBLIC); !a_it.atEnd(); ++a_it)
{
source_attr = a_it.attrib();
dest_gah = geo2->findPrimAttrib(*source_attr);
if (dest_gah.isInvalid())
geo2->addPrimAttrib(source_attr);
}
const GA_Attribute *source_attr;
const GA_AttributeDict *dict;
GA_AttributeDict::iterator a_it;
GA_RWAttributeRef dest_gah;
dict = &geo1->pointAttribs();
for (a_it=dict->begin(GA_SCOPE_PUBLIC); !a_it.atEnd(); ++a_it)
{
source_attr = a_it.attrib();
dest_gah = geo2->findPrimAttrib(*source_attr);
if (dest_gah.isInvalid())
geo2->addPrimAttrib(source_attr);
}

thank you,
I simplify and modify it for my purpose:
GA_Attribute* src_attr;
GA_FOR_ALL_PRIMITIVE_ATTRIBUTES(input_1, src_attr)
{
gdp->addPointAttrib(src_attr);
}
PS: I think its not necessary to test if attribute is valid, It works fine
