参数选项，加载病毒都浏览得七七八八了，这里就贴个简单的函数注释吧。哈哈。
代码注释如下：
int cli_load(const char *filename, struct cl_engine **engine, unsigned int *signo, unsigned int options, struct cli_dbio *dbio)
{
FILE *fs = NULL;
int ret = CL_SUCCESS;
uint8_t skipped = 0;
const char *dbname;
//打开病毒库文件
if(!dbio && (fs = fopen(filename, "rb")) == NULL) {
cli_errmsg("cli_load(): Can't open file %s
", filename);
return CL_EOPEN;
}
//不清楚下面宏定义为啥被忽略了
//路径分隔符windows的应该不是/的
/*
#ifdef C_WINDOWS
if((dbname = strrchr(filename, '\')))
#else
*/
//将dbname定位到文件名位置
if((dbname = strrchr(filename, '/')))
/*#endif */
dbname++;
else
dbname = filename;
