/* cmfnc.h
**
** This file contains function-specific symbols and declarations needed
** by application programs that wish to make use of the ccmd package.
** It is generated by m4 by means of the cmfnc.h4 file in conjunction with
** individual configuration files (as in cm???.cnf).  The initial portion
** of the file, including this comment, is copied verbatim from the file
** cmfnc.top.
**
** Function codes are given names like _CMTTT, where TTT is the three-
** letter abbreviation for the type, and are assigned small positive
** integer values.
**
** Function-specific error codes are given names of the form TTTxEEE,
** where TTT is the three-letter abbreviation for the parse type, and
** EEE is an abbreviation for the error.  The values assigned to these
** symbols are in two parts.  The left half contains the function code
** for the parse function, and the right half contains an integer
** in the range 0 to n-1, where there are n errors defined for the parse
** type.  Generic error codes for the ccmd package as a whole are given
** names like CMxEEE, and have zeros in the left half.
**
** Flag values are generally given names like TTT_FFF, where FFF is a
** mnemonic for the flag.  Other constants are given names like _TTTCCC,
** where CCC is a mnemonic for the constant.
