2014-04-01misc: Fix safe vsnprintf() function.Simon Howard
An off-by-one error in the function caused the strings to be truncated one character too early. Change the return value check so that negative values are also interpreted as indicating truncation; this is the behavior of the Win32 API.
2014-04-01misc: Tweak safe string functions slightly.Simon Howard
Properly handle cases where a very small string buffer is specified.
2014-04-01Replace all snprintf() calls with M_snprintf().Simon Howard
The Windows API has an _snprintf function that is not the same as Unix's snprintf(): if the string is truncated then no trailing NUL character is appended. This makes the function unsafe. Define a replacement/wrapper called M_snprintf that works the same but always appends a trailing NUL, for safety on Windows and other OSes that behave like this. Do the same thing for vsnprintf(), and update HACKING to list snprintf/vsnprintf as forbidden functions. This fixes #375; thanks to Quasar for pointing out the different behavior of these functions.
2014-03-30Eliminate some uses of sprintf() from common code.Simon Howard
As part of this, add DIR_SEPARATOR_S as a string version of the DIR_SEPARATOR macro. Change M_TempFile() to return a string allocated on the C heap rather than the zone heap. This is a first step towards fixing #371.
2014-03-29misc: Make arguments to string functions const.Simon Howard
Where a pointer is to a buffer that does not need to be mutable for the operation of the function, use const char * instead. This avoids some type errors where constant string are passed.
2014-03-29misc: Add M_StringConcat.Simon Howard
Just as M_StringCopy behaves the same as strlcpy(), M_StringConcat behaves the same as strlcat(). Use this in one location.
2014-03-29misc: Add string utility functions.Simon Howard
It's more readable to write "M_StringEndsWith(..." than doing a bunch of pointer arithmetic, and this is a common pattern. Also add M_StringStartsWith, M_StringJoin and M_StringCopy. The latter is a safe alternative for strcpy() that works the same as OpenBSD's strlcpy(). Use these functions in a few places where it makes sense.

2008-01-20Refactor the video mode configuration system.Simon Howard
The previous system was built around the program choosing a screen mode from the user's settings, this is based around choosing settings from the specified screen mode. As such, the old screenmultiply config variable is now gone. Also, aspect ratio correction is now on by default. Add new aspect ratio correction functions for horizontal squashing (as a complement to the existing vertical stretching). Subversion-branch: /trunk/chocolate-doom Subversion-revision: 1005
