Subject: endpoint_t in syslib
X-Git-Tag: v3.1.5~105
X-Git-Url: http://zhaoyanbai.com/repos/?a=commitdiff_plain;h=b900311656476c1e03a790bb49084a56238fd1e8;p=minix.git

endpoint_t in syslib

- headers use the endpoint_t in syslib.h and the implmentation was using int
  instead. Both uses endpoint_t now

- every variable named like proc, proc_nr or proc_nr_e of type endpoint_t has
  name proc_ep now

- endpoint_t defined as u32_t not int
