Fixed bug 4283 - SDL's version of memset is different from libc's
...
janisozaur
memset's documentation reads:
* The memset() function shall copy c (converted to an unsigned char) into each of the first n bytes of the object pointed to by s. (http://pubs.opengroup.org/onlinepubs/9699919799/functions/memset.html )
* Sets the first count characters of dest to the character c. (https://msdn.microsoft.com/en-us/library/1fdeehz6.aspx )
* write a byte to a byte string (https://developer.apple.com/library/archive/documentation/System/Conceptual/ManPages_iPhoneOS/man3/memset.3.html )
The highlight here is they all mean a single _byte_, even though memset receives a parameter of type int, which can hold more data than a single byte. SDL's implementation of memset, however, does not clear any of the higher bits, causing an erroneous behaviour when passed an argument bigger than 0xff.

make sure SDL_vsnprintf() nul terminates if it is using _vsnprintf
...
The change makes sure that SDL_vsnprintf() nul terminates if it is
using _vsnprintf() for the job.
I made this patch for Watcom, whose _vsnprintf() doesn't guarantee
nul termination. The preprocessor check can be extended to windows
in general too, if required.

Fixed bug 3284 - minor correction for SDL_setenv on _WIN32__ platform
...
Coriiander
Here is a minor correction for a non-breaking mistake in SDL_setenv for __WIN32__ platform. See below for details.
FILE:
"SDL/src/stdlib/SDL_getenv.c"
FUNCTION: (__WIN32__ platform)
int SDL_setenv(const char *name, const char *value, int overwrite)
CODE:
if (!overwrite) {
char ch = 0;
const size_t len = GetEnvironmentVariableA(name, &ch, sizeof (ch));
if (len > 0) {
return 0; /* asked not to overwrite existing value. */
}
}
WHAT'S WRONG:
The 3th argument to GetEnvironmentVariable (being DWORD nSize) must be the number of characters, not the number of bytes. SDL currently passes "the size of 1 char", rather "1". While it is non-breaking (1=1 after all), it is incorrect. Furthermore there is no need to specify the 2nd and 3th arguments at all.
CORRECTION 1: (corrected argument_
if (!overwrite) {
char ch = 0;
const size_t len = GetEnvironmentVariableA(name, &ch, 1);
if (len > 0) {
return 0; /* asked not to overwrite existing value. */
}
}
CORRECTION 2: (stripped of unneeded code)
if (!overwrite) {
if (GetEnvironmentVariableA(name, NULL, 0) > 0) {
return 0; /* asked not to overwrite existing value. */
}
}
