* Remove and simplify an impossible case (if *p = memchr(cp, 0, prec),ray2007-01-301-9/+7
| | | | | | | | | | | p - cp cannot be greater than prec). Prevent an integer overflow when printing a string with length greater than INT_MAX. Initial diff from millert@. OK millert@, beck@, and otto@.

| | | | OK and input from deraadt, jmc, millert.
* check mmap for failure. the helper functions using it return -1, buttedu2006-04-291-36/+43
| | | | | | | callers do not yet check since printf() for example is not documented to return an error. some formatting cleanups. mostly ok deraadt millert

| | | | | | | for such a small diff, this one was hard work... based on a diff from ray lai; blood, sweat, and tears (and ok) kettenis

* in code fragment:jmc2006-01-061-14/+14
| | | | | | | | | | | - allocate enough space for sfn. - remove variable initializations that get overwritten anyway. - change spaces to tabs. - change "sizeof sfn" to "sizeof(sfn)". - change fprintf(stderr) to warn(). from ray lai; ok millert

* clarify the description of append mode;jmc2005-11-141-2/+7
| | | | | this comes originally from a mail from mpech@; ok otto@, and no one else objected;
* fix a few warnings, keep the crypt stuff for later.espie2005-10-102-3/+4

* - simplify descriptions of stream positioning in various open modesjaredy2005-07-261-8/+15

| | | | | - add $OpenBSD$ tag - a couple minor tweaks

* Fix rearranging of parameters for quad types.espie2005-06-081-11/+24
| | | | | | | Use stateful functions for mbtowc. Use the same loop for scanning and for rescanning the format. okay millert@

* Move the va_start()/va_end() pair such that it directly backets the callmillert2005-05-282-8/+7
| | | | | to vfprintf() like the rest of the *printf functions. This is clearer and makes the error case in asprintf() simpler. From Andrey Matveev.

* let vfscanf be a real function. Use a weak_alias on systems where thisespie2005-05-117-12/+42

* Change internals of FILE: reuse the unget buffer field to access anespie2005-04-3014-41/+128
| | | | | | | | | | | | | | | | extended attribute data structure (pimpl idiom). Idea taken from citrus. Much discussion with deraadt@, otto@, millert@... This is the least disruptive way to extend FILE, since its size can't really change without this being a flag day. So the size doesn't change. Actual additions to the structure will come in separate steps, since this change is nasty enough on its own. Tests by otto@ and others, careful reading of code by otto@ and millert@. This is definitely a major bump, and has been checked to not impact a full ports build.
