Hello, Probably this mail should go to the internals list :)
I was looking into MySQL Client libaray and I could figure out the DATA are kept as linked list of MYSQL_ROW structure i.e. in MYSQL_ROWS being one node. Now MYSQL_ROW is typedefed as char** that is array of strings. Looking into the mysql_fetch_lengths() API code, the lengths are calculated from the offset between pointers. Forgive my C knowledge, but I was unable to understand how we are calculating thru offset. As far as I can understand this is what is happening: A MYSQL_ROW is allocated with field_count number of indexes. Each index is then again my_alloced() to store information about each each and so on. i.e. myrow = malloc ( sizeof (char*), field_count ); myrow[0] = malloc ( sizeof(char), field_data ); myrow[1] = malloc ( sizeof(char), field_data ); myrow[2] = malloc ( sizeof(char), field_data ); .... In this case how can we calculate lengths using offsets? Or I am missing something very stupid. A little clarity will do hell lot of good to me :) Any pointers...
