请问谁用过libbzip2压缩过文件?
我下载了一个并做了一个DLL, 但编译时总出问题.
如:bzWriteClose() 有5个参数而例子有1或2个参数.

FILE* f;
BZFILE* b;
int nBuf;
char buf[1024 ];
int bzerror;
int nWritten;

f = fopen ( "myfile.bz2", "w" );
if (!f) {
/* handle error */
}
b = bzWriteOpen ( &bzerror, f, 9 );
if (bzerror != BZ_OK) {
bzWriteClose ( b );
/* handle error */
}

while ( 1 ) {
/* get data to write into buf, and set nBuf appropriately */
nWritten = bzWrite ( &bzerror, b, buf, nBuf );
if (bzerror == BZ_IO_ERROR) {
bzWriteClose ( &bzerror, b );
/* handle error */
}
}

bzWriteClose ( &bzerror, b );
if (bzerror == BZ_IO_ERROR) {
/* handle error */
}
