NAME

       mtext_tok - Look for a token in an M-text.

SYNOPSIS

       MText* mtext_tok (MText * mt, MText * delim, int * pos)

DESCRIPTION

       Look for a token in an M-text. The mtext_tok() function searches a token that firstly occurs after
       position pos in M-text mt.  Here, a token means a substring each of which does not appear in M-text
       delim.  Note that the type of pos is not int but pointer to int.

RETURN VALUE

           If a token is found, mtext_tok() copies the corresponding part of mt and returns a pointer to the
           copy. In this case, pos is set to the end of the found token. If no token is found, it returns NULL
           without changing the external variable merror_code.  If an error is detected, it returns NULL and
           assigns an error code to the external variable merror_code.

ERRORS

           MERROR_RANGE
