# Synopsis

PDX_MSGT s203_InitModelInfo(long option, MDA_MODEL_INFO *model_info)

# Purpose

Setup model to contain STEP data.

# Description

The model information structure is filled in with the appropriate defaults for the STEP interface. The model_info struct should first be initialized by calling mda_GetModelDefaults. The model information will be set so that mda_ParseFile invokes the STEP interface function safp_ParseFile and mda_FormatFile invokes saff_FormatFile. See the appropriate manual page for more information on these functions. Only the following fields in model_info can be modified by the application after this function is called:

.nf modelnam validate backptrs allocate Free setcur udata .fi

The ddf will automatically be set up to use the IS version of the AP 203 schema.

The backptrs field is set to on (1) by default.
