From ee1de6a067c70fbd8cb73facd64c3b0b275f9f83 Mon Sep 17 00:00:00 2001 From: deischen Date: Wed, 24 Jan 2001 13:03:38 +0000 Subject: Add weak definitions for wrapped system calls. In general: _foo - wrapped system call foo - weak definition to _foo and for cancellation points: _foo - wrapped system call __foo - enter cancellation point, call _foo(), leave cancellation point foo - weak definition to __foo Change use of global _thread_run to call a function to get the currently running thread. Make all pthread_foo functions weak definitions to _pthread_foo, where _pthread_foo is the implementation. This allows an application to provide its own pthread functions. Provide slightly different versions of pthread_mutex_lock and pthread_mutex_init so that we can tell the difference between a libc mutex and an application mutex. Threads holding mutexes internal to libc should never be allowed to exit, call signal handlers, or cancel.
