* Changed fflush() behavior to no-op for r/w streams in read-mode.Manuel Novoa III2002-08-061-17/+33
| | | | | | | | | | | | | This falls under undefined behavior wrt ANSI/ISO C99, but SUSv3 seems to treat it as a no-op and it occurs in some apps. Fixed a problem with _stdio_fwrite() not checking for underlying write() failures. Fixed both _stdio_fwrite() and _stdio_fread() to make sure that the putc and getc macros were disabled if the stream was in and error state. The above changes should take care of a problem initially reported by "Steven J. Hill" <sjhill@realitydiluted.com>.

* Enable WCHAR support for C/POSIX stub locales.Manuel Novoa III2002-07-031-134/+244
| | | | | | Implemented unformatted wide i/o functions. (ungetwc still needs testing) Fix a few bugs in wchar.c. Modifications for bcc/elks support.
* Fix perror() and printf("%m") to not call strerror(), as required by theManuel Novoa III2002-06-181-5/+48
| | | | | | | | | standards. Temporarily added a utility function to wrap Erik's strerror_r so that "Unknown error xxx" strings can be generated for errno's which cause strerror_r to fail. That utility function will eventually be merged in with the strerror/strerror_r functions when I change over to optionallly mmap'ing the system error strings to provide for lower mem comsumption on non-MMU platforms, as well as locale-specific system error messages.
* Revert Erik's patch to vasprintf and fix the real issue.Manuel Novoa III2002-06-111-0/+1
| | | | | The writer for the stream returned by open_memstream was supposed to keep the buffer nul-terminated. I apparently left out a statement.
* Fix the read/write auto-transition bugs. Note that if we can'tManuel Novoa III2002-04-091-29/+36
| | | | | | | | | | | | auto-transition, we fail the operation. This is different than glibc's apparent behavior for writing of clearing the read buffer and still failing the write without setting the stream's error flag. Also, change a number of "errno = xxx" assignments to use __set_errno(). Also, change setvbuf(file, NULL, _IO{LF}BF, 0) behavior to more closely match glibc's by keeping the current buffer and only changing the buffering mode. Update setlinebuf() in the process to match the man page behavior.

* Per discussion with Manuel, when we call __stdio_flush_buffersEric Andersen2002-02-231-1/+9

| | | | | | | | | | avoid problems with fgets on tty streams. I actually did some testing this time. ;-) Note: there is a difference in behavior between glibc and uClibc here regarding fread() on a tty stream. glibc's fread() seems to return after reading all _available_ data even if not at end-of-file, while uClibc's fread() continues reading until all requested or eof or error. The latter behavior seems correct w.r.t. the standards.

* Fix include/errno.h to not use kernel header, and instead use bits/errno.h.Eric Andersen2001-04-061-7/+7
| | | | | | | This required we use _LIBC instead of __LIBC__ to be consistent with glibc. This had some sideffects in sys/syscalls.h. While fixing things, I made everything use __set_errno() for (eventual) thread support. -Erik
