fc1a83184b add and "f" flag to fopen that makes sure we are opening a plain file, 
so that there is no chance to block.

d896261208 back out the #ifdef _DIAGNOSTIC argument checks; too many people complained. 
_DIAGASSERT() is still retained.

e0f82c3ae3 revert previous; if we examine SUS more closely we find that unless explictly specified, use of a NULL pointer is undefined 1999-09-17 13:03:46 +00:00
lukem
3471ac6647 return (0) if size or count == 0 before check for _DIAGASSERT(buf != NULL). 
this is ok according to SUS.

b48252f365 * use _DIAGASSERT() to check pointer arguments against NULL and file 
descriptors against -1 (as appropriate).
* add actual checks which to detect stuff that would trigger_DIAGASSERT(),
  and attempt to return a sane error condition.
* knf some code
* remove some `register' decls.

the first two items result in the addition of code similar to the
following in various functions:

		_DIAGASSERT(path != NULL)
	#ifdef _DIAGNOSTIC
		if (path == NULL) {
			errno = EFAULT;
			return (-1);
		}
	#endif

38c96853cf Last of the .Os cleanups. .Os is defined in the tmac.doc-common file, 
so we shouldn't override it with versions in the manpages.  Wheee!

55cb8b09ce Functionally back out namespace.h revision 1.7 and perror.c revision 1.15; 
perror() is an identifier reserved by ANSI/ISO C, and in case of a redefition
the behavior is undefined.

3b7ac44e6c * Add const keywords to function arguments as appropriate. 
* Clarify the description of the initial position of the stream (some confusion
  due to the way fdopen() was merged into a former ANSI-only document).

cb697ba0d0 When reopening in append mode, seek to the end of file in order to have the 
internally kept offset pointer reflect this; ftell(3) would report an
incorrect current offset otherwise.  From Geoff C. Wing in lib/6381.

8e8595b01c Need to wrap stdio stream locking around the function body. On the bright

6de55982d6 * Wrap file locking around the function body in order to have fseek() and 
clearerr() executed as a single unit.

d1d407360d This is ugly. There is a const castaway inside the print macro, so we cannot 
use /* LINTED */ comments, since cpp will expand comments only at the macro
definition location, not at every expansion.

56068ec670 Don't return immediately if EOF encountered while matching format string white

the (format string) white space that do not operate on the input stream,

ef3079f0ee Make sure we free the buffer in all error cases. 
Do the final realloc(3) to the size of the string, not the size of the buffer
allocated for the string (which is a noop).
