To be consistent, use the __weak_reference macro from <sys/cdefs.h> 2001-04-10T04:19:21Z Daniel Eischen deischen@FreeBSD.org 2001-04-10T04:19:21Z urn:sha1:437df4859af22264a2c620a3720c776bf0c4a58d instead of #pragma weak to create weak definitions. Suggested by: bde Add weak definitions for wrapped system calls. In general: 2001-01-24T13:03:38Z Daniel Eischen deischen@FreeBSD.org 2001-01-24T13:03:38Z urn:sha1:e5106342c6de9cbe26c4827e4e29bae309cd8cfb _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. Approved by: -arch -Wall and minor style(9) cleanups. 1999-12-28T18:13:04Z Daniel Eischen deischen@FreeBSD.org 1999-12-28T18:13:04Z urn:sha1:1752e66d49ea5d9653b0cec4df9949774de0b806 $Id$ -> $FreeBSD$ 1999-08-28T00:22:10Z Peter Wemm peter@FreeBSD.org 1999-08-28T00:22:10Z urn:sha1:7f3dea244c40159a41ab22da77a434d7c5b5e85a Add RCS IDs to those files without them. 1999-08-05T12:15:30Z Daniel Eischen deischen@FreeBSD.org 1999-08-05T12:15:30Z urn:sha1:fa7c4d557556a90c64eaf10038c0d2a685801357 Fix copyrights (s/REGENTS/AUTHOR).

This looks like a big change but it isn't. It should reduce the size of libc_r and make it run slightly faster. Simplify the handling of thread specific data.

POSIX says that once a key is deleted, using the key again results in undefined behaviour.
