SysCacheGetAttr(). There are examples all over the tree, but
one that's specific to proargmodes (and also illustrates the
best practices for deciphering its value) is in
parser/analyze.c's transformCallStmt().
You should also ask yourself if you really *need* to examine
proargmodes for yourself, or if there's a utility function
somewhere that will compute what you need to know.
