[unixODBC-support] Determining the size of a blob?

I'm relatively new to odbc and would like to know if there is any way 
to determine the size of a blob so I can allocate an adequate size 
buffer to copy it into. I'm mainly interested in storing text that 
doesn't fit into a varchar field.

I'm trying to branch out from being MySQL dependent and the unixODBC 
driver seems like a great way to generalize to many databases at once. 
I've found it very straight forward to do most things so far, this is 
the last obstacle in my path currently. Any pointers to the use of 
blobs with odbc would be appreciated.
