Function getalias 

Source 
pub fn getalias(
    _alht: *mut HashTable,
    _ht: *mut HashTable,
    name: &str,
    flags: i32,
) -> Option<Param>
Expand description

Direct port of getalias(HashTable alht, UNUSED(HashTable ht), const char *name, int flags) from Src/Modules/parameter.c:1900. C body (c:1906-1919):

pm.node.nam = name;
assignaliasdefs(pm, flags);
if (al = alht[name]; flags == al->node.flags)
    pm->u.str = al->text;
else { pm->u.str = ""; flags |= PM_UNSET|PM_SPECIAL; }

alht selects which alias table to query: aliastab for raw / global aliases, sufaliastab for suffix aliases. Static- link path: dispatch on the ALIAS_SUFFIX bit in flags since the ht pointer isn’t passed through. Port of getalias(HashTable alht, UNUSED(HashTable ht), const char *name, int flags) from Src/Modules/parameter.c:1901. WARNING: param names don’t match C — Rust=(_alht, _ht, flags) vs C=(alht, ht, name, flags)
