2014-05-01opl: Fix crash when using OPL music.Simon Howard
The previous change to add the poll method to the music module interface introduced a crash, as the OPL music struct does not define a poll method.
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.
