-* the char
-* after the delimiter. Leading delimiters are skipped.
-*
-* Parameters:
-* string (mod) Ptr to string ptr, updated by token.
-* delimiters (in) Set of delimiter characters.
-* tokdelim (out) Character that delimits the returned token. (May
-* be set to NULL if token delimiter is not required).

+/****************************************************************************
+* Function: bcmstrtok
+*
+* Purpose:
+* Tokenizes a string. This function is conceptually similiar to ANSI C strtok(),
+* but allows strToken() to be used by different strings or callers at the same
+* time. Each call modifies '*string' by substituting a NULL character for the
+* first delimiter that is encountered, and updates 'string' to point to the char
+* after the delimiter. Leading delimiters are skipped.
+*
+* Parameters:
+* string (mod) Ptr to string ptr, updated by token.
+* delimiters (in) Set of delimiter characters.
+* tokdelim (out) Character that delimits the returned token. (May
+* be set to NULL if token delimiter is not required).
+*
+* Returns: Pointer to the next token found. NULL when no more tokens are found.
