Most error messages have an associated error number.  By looking up the
number in the list below you can obtain additional information about the
cause of the error.  This information is also available from a
self-extracting executable msg.exe, found on the PC-lint
distribution diskette, which produces the machine-readable ASCII file
msg.txt.  For FlexeLint users, the file msg.txt can be found on
the FlexeLint Supplementary diskette.

Messages numbered 1000 and higher pertain generally to C++.  This is
summarized in the table below.

After a possible 1000 is subtracted off, the remainder lies in the range
0-999.  Remainders in the range 1-199 are syntax errors, 200-299 are PC-lint/FlexeLint
internal errors and should never occur, 300-399 are fatal errors usually
brought about by exceeding some limit, 400-699 are warning messages that
indicate that something is likely to be wrong with the program being
examined.  Remainders in the range 700-899 designate informational messages.
These may be errors but they also may represent legitimate programming
practices depending upon personal programming style.  Remainders in the
range 900-999 are called "Elective Notes".  They are not automatically
output.  You may examine the list to see if you wish to be alerted to
any of them.

                                Glossary

A few of the terms used in the commentary below are:

argument  The actual argument of a function as opposed to a dummy (or
          formal) parameter of a function (see parameter).

arithmetic  any of the integral types (see below) plus float, double, and
          long double.

Boolean   In general, the word Boolean refers to quantities that can be
          either true or false.  An expression is said to be Boolean
          (perhaps it would be better to say 'definitely Boolean') if it
          is of the form: operand op operand where op is a relational (>
          >= < <=), an equality operator (== !=), logical And (&&) or
          logical Or (||).  A context is said to require a Boolean if it
          is used in an if or while clause or if it is the 2nd
          expression of a for clause or if it is an argument to one of
          the operators:  && or ||.  An expression needn't be definitely
          Boolean to be acceptable in a context that requires a Boolean.
          Any integer or pointer is acceptable.

declaration  gives properties about an object or function (as opposed to a
           definition).

definition  that which allocates space for an object or function (as
          opposed to a declaration) and which may also indicate
          properties about the object.  There should be only one
          definition for an object but there may be many declarations.

integral  a type that has properties similar to integers.  These include
          char, short, int, and long and the unsigned variations of any
          of these.

scalar    any of the arithmetic types plus pointers.

lvalue    is an expression that can be used on the Left hand side of an
          assignment operator (=).  Some contexts require lvalues such
          as autoincrement (++) and autodecrement (--).

macro     an abbreviation defined by a #define statement.  It may or may
          not have arguments.

member    elements of a struct and of a union are called members.

module    That which is compiled by a compiler in a single independent
          compilation.  It typically includes all the text of a .c (or a
          .cpp or .cxx, etc.) file plus any text within any #include
          file(s).

parameter A formal parameter of a function as opposed to an actual
          argument (see argument).


                           Message Parameters

Some of the messages are parameterized with one or more of the following
italicized names:

Char      Some character

Context   Specifies one of several contexts in which an assignment can
          be made.  Can be one of:

     o    assignment -- refers to an explicit assignment operator.
     o    return -- refers to the implied assignment of a return
          statement. The type of the expression is converted implicitly
          to the type of the function.
     o    initialization -- refers to the assignment implied by an
          initialization statement.
     o    arg. no.... -- refers to the implied assignment of an argument
          in the presence of a prototype.  The type of the expression is
          implicitly converted to the type within a prototype.
     o    arg. 'this' -- refers to the implied argument of a member
          function call.


FileName  A filename.  Messages containing this parameter can be
          suppressed with the -efile( ... ) option.

Integer   Some integer

Invocation  A function call with argument types.  To suppress a message
          containing an Invocation you need the complete call, not just
          the function name.  For example, the call f(1) could result in
          Error 1024 parameterized by 'f(int)'.  To suppress this
          message you could use -esym(1024,f(int)).  You could also use
          wild cards as in -esym(1024,f*).

Kind      A list of control structures.

Location  A line number followed optionally by a filename (if different
          from the current) and/or a module name if different from the
          current.

Name      A string, usually an identifier, that can be suppressed with a
          -esym but not with -elibsym.

String    A sequence of characters identified further in the message
          description.

Symbol    The name of a user identifier referring to a C or C++ object
          such as variable, function, structure, etc.  Messages
          containing this parameter can be suppressed with the -esym(
          ... ) option.  For C++, if Symbol is the name of a function
          the full function signature (including parameters) is given.
          Error suppression with -esym does not require (nor want) the
          parameters.

Type      A type or a top type base is provided.  A top type base is one
          of pointer, function, array, struct, union, or enum.

TypeDiff  specifies the way in which one type differs from another.
          Because of type qualification, function prototypes, and type
          compounding, it may not be obvious how two types differ.
          Also, see the -etd option to inhibit errors based on type
          differences.  TypeDiff can be one or more of:

     o    basic -- The two types differ in some fundamental way such as
          double versus int.

     o    count -- Two function types differ in the number of arguments.

     o    ellipsis -- Two function types differ in that one is
          prototyped using an ellipsis and the other is not prototyped.
