Errors and Warnings

Syntax and semantic errors typically occur in the source program. They identify actual programming errors. When an error is encountered, the compiler attempts to recover from the error and continue processing the source file. As more errors are encountered, the compiler outputs additional error messages. No object file is produced once an error is encountered.

Warnings produce information about potential problems which may occur during program execution. Warnings do not hinder compilation of the source file.

Errors and warnings are formatted as follows:

*** ERROR number IN LINE line OF file: message

*** WARNING number IN LINE line OF file: message

Where

number	is the error number.
line	is the line number where the error was detected.
file	is the source or include file in which the error was detected.
message	is a brief description of the error or warning.

The error or warning message may include the following terms:

Term	Description
character	Specifies a character.
class	Specifies the stored class of an object.
file-name	Specifies the name of a file on disk.
function-name	Specifies the name of a function in your program.
identifier	Specifies a user-defined name for a program object (function, variable, label, and so on).
L-Value	Specifies the location value of the variable. L-Values may be read-from or written-to.
macro-name	Specifies the name of a macro.
memory-space	Specifies the memory space where an object is located.
message	Specifies a content-specific error or warning message.
number	Specifies a number appropriate to the error or warning message.
operator	Specifies the operator used.
R-Value	Specifies the data value of the variable. The "R" may be thought of as "read" value. R-Values may be read-from but may not be written-to.
range	Specifies a range of values.
tag-name	Specifies the name of a struct, union, or enum.
token	Specifies a C language token or keyword.
type	Specifies the memory type used.

Errors and warnings are listed in numerical order and are divided into several sections:

Summary	Briefly describes the error or warning.
Description	Provides a detailed description of message and why it was generated.
Cause	Describes the cause of the error.
Resolution	Provides hints and suggestions for correcting the problem.
Example	Provides an example, where possible, of the error condition.
See Also	Provides useful references to additional material.
