Load mesh from a file.

Method all readers must provide to import a mesh.

Parameters

file_name	The file to read.
file_set	Optional pointer to entity set representing file. If this is not NULL, reader may optionally tag the pointed-to set with format-specific meta-data.
subset_list	An optional struct pointer specifying the tags identifying entity sets to be read.
file_id_tag	If specified, reader should store for each entity it reads, a unique integer ID for this tag.

virtual

Read tag values from a file.

Read the list if all integer tag values from the file for a tag that is a single integer value per entity.

Parameters

file_name	The file to read.
tag_name	The tag for which to read values
tag_values_out	Output: The list of tag values.
subset_list	An array of tag name and value sets specifying the subset of the file to read. If multiple tags are specified, the sets that match all tags (intersection) should be read.
subset_list_length	The length of the 'subset_list' array.
