BZip2 c++ error

[Geky]

I'm trying to use BZip2 library but I receive always an access
violation error. I use two different codes:

bz_stream bzstream;
ZeroMemory(&bzstream, sizeof(bzstream));


bzstream.bzalloc=NULL;
bzstream.bzfree=NULL;
bzstream.opaque=NULL;


int x = BZ2_bzCompressInit(&bzstream, 5, 0, 30);


BZ2_bzCompressInit(&bzstream, 5, 0, 30); <-- HERE IT RETURN
THE ERROR


if I use "bz_stream* bzstream" in place of "bz_stream bzstream" my
compiler says that "local variable 'bzstream' used without having been
initialized" :-(.


+++++++++++++++++++++++++++++


char pOrig[256], pComp[256], pDec[256];
unsigned int OrigLen, CompLen, DecLen;


strcpy(pOrig, "OMFG PIE! OMFG PIE! OMFG PIE! OMFG PIE! OMFG
PIE! OMFG
PIE!OMFG PIE! OMFG PIE! OMFG PIE! OMFG PIE! OMFG PIE! OMFG PIE! OMFG
PIE! OMFG PIE! OMFG PIE! OMFG PIE! OMFG PIE! OMFG PIE! OMFG PIE! OMFG
PIE!");
OrigLen = strlen(pOrig) + 1;
printf("Original:\t%s\nOrig Len:\t%d\n\n", pOrig, OrigLen);


CompLen = 256;
BZ2_bzBuffToBuffCompress(pComp, &CompLen, pOrig, OrigLen, 9,
0, 30); <-- HERE THERE IS THE ERROR AGAIN


I can't understand why there is this access violation always here and
with two different codes

Anyone know how to use bzlib?
