* Simplify sytem call renaming. Instead of _foo() <-- _libc_foo <-- foo(),Jason Evans2000-01-271-12/+12
| | | | | | | | | | | | | | | | | | | | just use _foo() <-- foo(). In the case of a libpthread that doesn't do call conversion (such as linuxthreads and our upcoming libpthread), this is adequate. In the case of libc_r, we still need three names, which are now _thread_sys_foo() <-- _foo() <-- foo(). Convert all internal libc usage of: aio_suspend(), close(), fsync(), msync(), nanosleep(), open(), fcntl(), read(), and write() to _foo() instead of foo(). Remove all internal libc usage of: creat(), pause(), sleep(), system(), tcdrain(), wait(), and waitpid(). Make thread cancellation fully POSIX-compliant.

* Add three-tier symbol naming in support of POSIX thread cancellationJason Evans2000-01-121-12/+14
| | | | | | | | | points. For library functions, the pattern is __sleep() <-- _libc_sleep() <-- sleep(). The arrows represent weak aliases. For system calls, the pattern is _read() <-- _libc_read() <-- read(). Notes: svn path=/head/; revision=55837

* vfork -> fork. The child calls execl() which calls malloc(), soBruce Evans1998-10-101-1/+1
| | | | | | | | | | | | vfork() can't be used. We could use alloca() in execl() so that it can be called between vfork() and execve(), but a "portable" popen() shouldn't depend on this. Calling execle() instead of execl() should be fairly safe, since execle() is supposed to be callable from signal handlers and signal handlers can't call malloc(). However, execle() is broken.

* Clean-up my modification of popen.c for vfork. Bruce's (this) is better.John Dyson1997-04-201-10/+12

* Fix the problem in popen that makes correct vfork semantics fail.John Dyson1997-04-161-6/+11
| | | | | | | | | Specifically, popen modifies a variable "pdes[1]" in the child in such a way that it breaks code in the parent (due to the address space sharing.) Notes: svn path=/head/; revision=24975
* Fixed cleaning up after malloc failure, which was broken by Lite2.Bruce Evans1997-03-111-3/+5
| | | | | | | | | We don't use socketpair(), so don't #include <sys/socket.h>. Restored some gcc-quieting parentheses that were lost in the Lite2 merge. Notes: svn path=/head/; revision=23734
