Here is the complete list of the error symbols in standard Emacs,
grouped by concept. The list includes each symbol’s message (on the
error-message
property of the symbol) and a cross reference to a
description of how the error can occur.
Each error symbol has an error-conditions
property that is a
list of symbols. Normally this list includes the error symbol itself
and the symbol error
. Occasionally it includes additional
symbols, which are intermediate classifications, narrower than
error
but broader than a single error symbol. For example, all
the errors in accessing files have the condition file-error
.
As a special exception, the error symbol quit
does not have the
condition error
, because quitting is not considered an error.

symbol
string; reference.
error
"error"
@xref{Errors}.
quit
"Quit"
@xref{Quitting}.
args-out-of-range
"Args out of range"
@xref{Sequences Arrays Vectors}.
arith-error
"Arithmetic error"
See /
and %
in @ref{Numbers}.
beginning-of-buffer
"Beginning of buffer"
@xref{Motion}.
buffer-read-only
"Buffer is read-only"
@xref{Read Only Buffers}.
cyclic-function-indirection
"Symbol's chain of function indirections contains a loop"
@xref{Function Indirection}.
domain-error
"Arithmetic domain error"
end-of-buffer
"End of buffer"
@xref{Motion}.
end-of-file
"End of file during parsing"
This is not a file-error
.
@xref{Input Functions}.
file-error
This error and its subcategories do not have error-strings, because the
error message is constructed from the data items alone when the error
condition file-error
is present.
@xref{Files}.
file-locked
This is a file-error
.
@xref{File Locks}.
file-already-exists
This is a file-error
.
@xref{Writing to Files}.
file-supersession
This is a file-error
.
@xref{Modification Time}.
invalid-function
"Invalid function"
@xref{Classifying Lists}.
invalid-read-syntax
"Invalid read syntax"
@xref{Input Functions}.
invalid-regexp
"Invalid regexp"
@xref{Regular Expressions}.
mark-inactive
"The mark is not active now"
no-catch
"No catch for tag"
@xref{Catch and Throw}.
overflow-error
"Arithmetic overflow error"
protected-field
"Attempt to modify a protected field"
range-error
"Arithmetic range error"
search-failed
"Search failed"
@xref{Searching and Matching}.
setting-constant
"Attempt to set a constant symbol"
The values of the symbols nil
and t
may not be changed.
@xref{Constant Variables, , Variables that Never Change}.
singularity-error
"Arithmetic singularity error"
tooltalk-error
"ToolTalk error"
@xref{ToolTalk Support}.

"Undefined keystroke sequence"

"Arithmetic underflow error"

"Wrong number of arguments"
@xref{Classifying Lists}.
wrong-type-argument
"Wrong type argument"
@xref{Type Predicates}.
These error types, which are all classified as special cases of
arith-error
, can occur on certain systems for invalid use of
mathematical functions.
