LRDRET lrd_ora8_lob_read( void * const mpvLRDDBIHandleSvcCtx, void * const mpvLRDDBIHandleLob, unsigned long const mjAmtToRead, unsigned long * const mpjAmtRead, unsigned long const mjOffset, unsigned long const mjBufl, unsigned short const mjCsid, unsigned char const mjCsfrm, int const miDBErrorSeverity );

mpvLRDDBIHandleSvcCtx A pointer to an LRDDBI Service Context Handle with a valid Server Handle attribute.
mpvLRDDBIHandleLob A pointer to an LRDDBI Lob Descriptor Handle.
mjAmtToRead The number of bytes to read
mpjAmtRead Pointer to number of bytes to read on output.
mjOffset Offset for start of read.
mjBufl The buffer length.
mjCsid The character set ID.
mjCsfrm The character set form.
