4935ab5243 printf() and vprintf() must use C buffered I/O if available. 
This backs out a part of PR 1179 which has a very serious error:  If C buffered I/O is available, then printf() and vprintf MUST use it.  Otherwise, the ordering of the I/O will be screwed up.  They must not use direct file descriptor I/O UNLESS C buffered I/O is disabled.

154a87993f fs/vfs/fd_open.c: fs_fdopen() must not set errno 
Functions within the OS must never set the errno value.  fs_fdopen() was setting the errno value.  Now, after some parameter changes, it reports errors via a negated errno integer return value as do most all other internal OS functions.

dc8c814ca3 Squashed commit of the following: 
Fixed coding standard error in several files.  Use of while( is incorrect; a space is required between while and (.  Also ran tools/nxstyle and fix thoses complaints as well in most files.

    Changes to comply with coding standard.  Mostly focused on files with missing space after keyword in if(, switch(, and for(.  Offending files also got changes to comply with tools nxstyle.  If there were logs of nxstyle complaints, the file also got a taste of tools/indent.sh.  Still need to fix occurrences of while( with missing space.  There are a lot of them.

0951151c33 libs/libc/pthread, syscall/, and include/sys/syscall.h: Support for pthread_mutex_timedlock() was added recently, however no new system call was added for the API make is usable only in the FLAT build. With a pthread_mutex_timedlock() system call, there is no reason for a pthread_mutex_lock() system call since it is now nothing more than an wrapper around pthread_mutex_timedlock(), passing NULL for the time value. The pthread_mutex_lock() syscall was removed and the pthread_mutex_lock() implemented was moved from /sched/pthread to where it now belows in libs/libc/pthread. 2019-02-25 18:19:13 -06:00
