Informix DataBlade API Programmer's Manual DataBlade API Function Descriptions

The mi_lo_specset_def_open() function sets the default open flags for a smart large object.

mi_integer mi_lo_specset_def_open(LO_spec, def_open_flags)

MI_LO_SPEC *LO_spec;

mi_integer def_open_flags;

LO_spec	is a pointer to the LO-specification structure in which to save the default open flags.
def_open_flags	is an integer value that specifies the bit mask of the default open flags for the smart large object.

The mi_lo_specset_def_open() function is the LO-specification accessor function that sets the default open flags for a new smart large object. The def_open_flags value is the bit mask that indicates which open flags to use when the mi_lo_open() opens the smart large object. The default open flags indicate how the mi_lo_open() function opens the smart large object when it does not include an open flag. To override the default open flags, you can specify an open mode as an argument to mi_lo_open().

See the descriptions of the following functions: mi_lo_copy(), mi_lo_create(), mi_lo_expand(), mi_lo_from_file(), mi_lo_open(), mi_lo_spec_free(), mi_lo_spec_init() and mi_lo_specget_def_open().

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