[Orclib-devel] oci lob call, why i can read/write only unsigned int if the lob can have a length big_uint ?

[Roberto M. <rob...@di...>]

Hello to All, 

just a little question, why when i read/write within a lob i can only
read/write unsigned int data

OCI_EXPORT unsigned int OCI_API OCI_LobRead (OCI_Lob *lob, void *buffer,
unsigned int len)  
OCI_EXPORT unsigned int OCI_API OCI_LobWrite (OCI_Lob *lob, void
*buffer, unsigned int len)  

if the size of the lob can be big_uint ?

OCI_EXPORT big_uint OCI_API OCI_LobGetLength (OCI_Lob *lob)

why dont use read/write operation with big_uint len ?

OCI_EXPORT unsigned int OCI_API OCI_LobRead (...,  big_uint len)  
OCI_EXPORT unsigned int OCI_API OCI_LobWrite (..., big_uint len) 

thanks
