242 The ACPI_PARSER structure describes the fields of an ACPI table and
243 provides means for the parser to interpret and trace appropriately.
245 The first three members are populated based on information present in
246 in the ACPI table specifications. The remaining members describe how
247 the parser should report the field information, validate the field data
248 and/or update an external pointer to the field (ItemPtr).
250 ParseAcpi() uses the format string specified by 'Format' for tracing
251 the field data. If the field is more complex and requires additional
252 processing for formatting and representation a print formatter function
253 can be specified in 'PrintFormatter'.
254 The PrintFormatter function may choose to use the format string
255 specified by 'Format' or use its own internal format string.
257 The 'Format' and 'PrintFormatter' members allow flexibility for
258 representing the field data.
