Informix DataBlade API Programmer's Manual DataBlade API Function Descriptions

The mi_lo_specget_maxbytes() accessor function obtains the maximum size of a smart large object (in bytes) from an LO-specification structure.

mi_integer mi_lo_specget_maxbytes(LO_spec, maxbytes)

MI_LO_SPEC *LO_spec;

mi_int8 *maxbytes;

LO_spec	is a pointer to the LO-specification structure from which to obtain the maximum size.
maxbytes	is a pointer to an eight-byte integer (mi_int8) value into which mi_lo_specget_maxbytes() puts the maximum size, in bytes, of the smart large object.

Yes	Yes

The mi_lo_specget_maxbytes() function is the LO-specification accessor function that returns the maximum size from a set of storage characteristics. The smart-large-object optimizer does not allow the size of a smart large object to exceed the maxbytes value.

Important: Before you call mi_lo_specget_maxbytes(), you must put storage characteristics into an LO-specification structure.

You can use any of the following functions to initialize the LO-specification structure:

• The mi_lo_colinfo_by_ids() or mi_lo_colinfo_by_name() function put storage characteristics that are associated with a particular CLOB or BLOB column in an LO-specification structure.
• The mi_lo_stat_cspec() function puts storage characteristics of an existing smart large object in an LO-specification.
• The mi_lo_specset_maxbytes() function sets the maximum size in an LO-specification structure.

The mi_lo_specget_maxbytes() function obtains the current value for the maximum size from the LO-specification structure that LO_spec references.

See the descriptions of the following functions: mi_lo_colinfo_by_ids(), mi_lo_colinfo_by_name(), mi_lo_spec_free(), mi_lo_spec_init(), mi_lo_specset_maxbytes(), and mi_lo_stat_cspec().

For more information on the maximum size of a smart large object, see Storage Characteristics. For information on how to use the mi_lo_specget_maxbytes() function, see The LO-Specification Structure, and Defining User-Specified Storage Characteristics.
