Post Form Help!!!!

okay i need help with post form

if i have a field like is on a web page on another server

<input type="password" name="passwd" size="16" maxlength="16">

to input the text i think i would do

char * uri = "http:\\www.someplace.com"
HTAssocList * formfields = HTAssocList_new();
HTAssocList_addObject(formfields, "password" , "vectra"); 
//vectra is the password
HTRequest * request = HTRequest_new();
HTRequest_setOutputFormat(request, WWW_SOURCE);
HTAnchor * anchor = HTAnchor_findAddress(uri);
HTChunk * result  = HTPostFormAnchorToChunk(formfields, anchor, request);
