Hi all~
Thank you for solving my problem before. I still have some other
questions when analysing the codes of ClamAV. Could anybody help me again?
What does the member variable uint32_t *soff stands for? Why sort the
elements which the soff point to? Is the qsort function in the code
implement the quick sort algorithm?
struct cli_matcher {
unsigned int type;
/* Extended Boyer-Moore */
uint8_t *bm_shift;
struct cli_bm_patt **bm_suffix, **bm_pattab;
struct cli_hashset md5_sizes_hs;
uint32_t *soff, soff_len; /* for PE section sigs */
uint32_t bm_offmode, bm_patterns, bm_reloff_num, bm_absoff_num;
/* Extended Aho-Corasick */
uint32_t ac_partsigs, ac_nodes, ac_patterns, ac_lsigs;
struct cli_ac_lsig **ac_lsigtable;
struct cli_ac_node *ac_root, **ac_nodetable;
struct cli_ac_patt **ac_pattable;
struct cli_ac_patt **ac_reloff;
uint32_t ac_reloff_num, ac_absoff_num;
uint8_t ac_mindepth, ac_maxdepth;
struct filter *filter;
uint16_t maxpatlen;
uint8_t ac_only;
#ifdef USE_MPOOL
mpool_t *mempool;
#endif
};
