[Original] A String Conversion Function commonly used in irrlicht

After irrlicht supports Chinese characters, the conversion from char * To wchar_t * is often used during programming. I read the article about l "XX" that was previously reproduced. Article , Write a small function for use. # define xmalloc (s) heapalloc (getprocessheap (), heap_zero_memory, (s ))
# Define xfree (p) heapfree (getprocessheap (), 0, (p) wchar_t * str2wstrptr (const char * pstr)
{
Pstr pmultibytestr = (pstr) pstr;
Pwstr pwidecharstr;
Int nlenofwidecharstr;
// Use the API function multibytetowidechar () to convert a to a Unicode Character
Nlenofwidecharstr = multibytetowidechar (cp_acp, 0, pmultibytestr,-1, null, 0 );
Pwidecharstr = (pwstr) xmalloc (nlenofwidecharstr * sizeof (wchar ));
Multibytetowidechar (cp_acp, 0, pmultibytestr,-1, pwidecharstr, nlenofwidecharstr );
Return pwidecharstr;
} Call str2wstrptr and use xfree to release the space applied by xmalloc. example: Char name [] = "years of silence"; wchar_t * pmyname = str2wstrptr (name); after conversion, it can be used in irrlicht: itextscenenode * Bill = scene-> addtextscenenode (fonts [1], pmyname); xfree (pmyname); you can skip scene-> addtextscenenode (fonts [1], L "silent years"); now.
