sra at hactrn.net pushed a commit to branch rpc
in repository sw/libhal.
commit e6f53e769aee1b8c08ab9c30ecbe191348817bbd
Author: Rob Austein <sra at hactrn.net>
AuthorDate: Thu May 12 20:23:42 2016 -0400
Fix buffer allocations in RPC client code.
The client wrappers for several RPC calls were not allocating enough
space for all of their arguments. Fixed, and added a bit of syntactic
sugar to make inspection a bit easier to combat the eyes-glazing-over
effect of an entire file full of nearly-identical RPC client stubs.
