/*************************************
|
|
* Function: pa_tokenize_tag
|
|
*
|
|
* Description: This function maps the passed in string
|
|
* to one of the valid tag element tokens, or to
|
|
* the UNKNOWN token.
|
|
*
|
|
* Params: Takes a \0 terminated string.
|
|
*
|
|
* Returns: a 32 bit token to describe this tag element. On error,
|
|
* which means it was not passed an unknown tag element string,
|
|
* it returns the token P_UNKNOWN.
|
|
*
|
|
* Performance Notes:
|
|
* Profiling on mac revealed this routine as a big (5%) time sink.
|
|
* This function was stolen from pa_mdl.c and merged with the perfect
|
|
* hashing code and the tag comparison code so it would be flatter (fewer
|
|
* function calls) since those are still expensive on 68K and x86 machines.
