That is because you never asked for that. Check your post #29, sub block sequences are printed based on that.

For removing f's. If in a single byte there is a trailing f, that will be masked.

Code:

#define DONT_PRINT1 0xff
#define DONT_PRINT2 0x0f
#define MASK 0x0f
#define INV_MASK 0xf0

void print_bytes(const unsigned char *ptr, int len, block bl)
{
        int i;
        unsigned char op;
        for(i=0;i<len;i++){
                if(MAIN_BLOCK == bl){
                        op = ptr[i] & MASK;

                        if(ptr[i] == DONT_PRINT1)
                                continue;

                        if(  ((i == (len-1)) && !(op ^ DONT_PRINT2)) 
                          || (!(op ^ DONT_PRINT2) && (ptr[i+1] && (ptr[i+1] == DONT_PRINT1))) ){

                                op = ptr[i] & INV_MASK;
                                if(op){
                                        printf("%x", op);
                                }
                                continue;
                        }
                }
                printf("%02x", ptr[i]);
        }
        printf("|");
        return;

}

void print_data(const unsigned char *ptr, int len, block bl)
{
        if(MAIN_BLOCK == bl){
                print_bytes(ptr, 1, bl);
                print_bytes(ptr+1, 3, bl);
                print_bytes(ptr+4, 8, bl);
                print_bytes(ptr+12, 8, bl);
        } else {
                print_bytes(ptr, 1, bl);
                print_bytes(ptr+1, 1, bl);
                print_bytes(ptr+2, 1, bl);
                print_bytes(ptr+3, 1, bl);
                print_bytes(ptr+4, 4, bl);
                print_bytes(ptr+8, 8, bl);
                print_bytes(ptr+16, 1, bl);
                if(*ptr == intrim_pat1[2][1]){
                        print_bytes(ptr+17, 1, bl);
                }
        }
        return;
}

votequorum_getinfo

VOTEQUORUM_GETINFO(3)				    Corosync Cluster Engine Programmer's Manual 			     VOTEQUORUM_GETINFO(3)

NAME

       votequorum_getinfo - Get information about the VoteQuorum service

SYNOPSIS

       #include <corosync/votequorum.h>

       int votequorum_getinfo(votequorum_handle_t *handle, unsigned int nodeid, struct votequorum_info *info);

DESCRIPTION

       The votequorum_getinfo function is used to get information about the voteing system and its nodes.

       The votequorum_info structure is defined as follows:

	      struct votequorum_info {
		  unsigned int node_id;
		  unsigned int node_votes;
		  unsigned int node_expected_votes;
		  unsigned int highest_expected;
		  unsigned int total_votes;
		  unsigned int quorum;
		  unsigned int flags;
	      };

	      #define VOTEQUORUM_INFO_FLAG_DIRTY      1
	      #define VOTEQUORUM_INFO_FLAG_DISALLOWED 2
	      #define VOTEQUORUM_INFO_FLAG_TWONODE    4
	      #define VOTEQUORUM_INFO_FLAG_QUORATE    8

       The members starting node_ hold information specific to the requested nodeid, the other are general to the voting system.

RETURN VALUE

       This call returns the CS_OK value if successful, otherwise an error is returned.

BUGS

       Callbacks are not support at the moment.

ERRORS

       The errors are undocumented.
