/*** TokStr - tokenize argument strings
|
|
*
|
|
* Purpose:
|
|
* Tokenize a string.
|
|
* Allocate space for a new string and copy each token in src into the
|
|
* new string and null terminate it. Tokens are whitespace delimited
|
|
* unless changed by specialdelims and/or tsflags. The entire tokenized
|
|
* string ends with 2 null bytes.
|
|
*
|
|
* TCHAR *TokStr(TCHAR *src, TCHAR *specialdelims, unsigned tsflags)
|
|
*
|
|
* Args:
|
|
* src - the string to be tokenized
|
|
* specialdelims - a string of other characters which are to be comsidered
|
|
* as token delimiters
|
|
* tsflags - bit 0 nonzero if whitespace are NOT delimiters
|
|
* bit 1 nonzero if special delimiters are tokens themselves,
|
|
* eg "foo=bar" => "foo0=0bar00"
|
|
*
|
|
* Returns:
|
|
* A pointer to the new string.
|
|
* A pointer to a null string if src is NULL
|
|
* NULL if unable to allocate memory.
|
|
*
|
|
* Notes:
|
|
* The format of the tokenized string dictates the way code is written
|
|
* to process the tokens in that string. For instance, the code
|
|
* "s += mystrlen(s)+1" is the way to update s to point to the next token
|
|
* in the string.
|
|
*
|
|
* Command considers "=", ",", and ";" to be token delimiters just like
|
|
* whitespace. The only time they are not treated like whitespace is
|
|
* when they are included in specialdelims.
|
|
*
|
|
* *** W A R N I N G ! ***
|
|
* THIS ROUTINE WILL CAUSE AN ABORT IF MEMORY CANNOT BE ALLOCATED
|
|
* THIS ROUTINE MUST NOT BE CALLED DURING A SIGNAL
|
|
* CRITICAL SECTION OR DURING RECOVERY FROM AN ABORT
