void errprt_c ( ConstSpiceChar * op,
SpiceInt lenout,
SpiceChar * list )
Retrieve or set the list of error message items
to be output when an error is detected.

VARIABLE I/O DESCRIPTION
-------- --- --------------------------------------------------
op I The operation: "GET" or "SET".
lenout I Length of list for output.
list I/O Specification of error messages to be output.
op indicates the operation to be performed. Possible
values are "GET" and "SET".
"SET" means, "the following list specifies the default
selection of error messages to be output." These are
the messages that will be output to the default error
output device (selected by errdev_c) when an error is
detected.
"GET" means, "return the current list of error output
items." This is the exact list that was set by the
last call to this routine with the "SET" option.
The option can be specified in mixed case. For example,
the following call will work:
errprt_c ( "SeT", lenout, "ALL" )
lenout is the allowed length of list when list is returning a
the error message list. The size described by lenout
should be large enough to hold any possible output plus 1.
list is a list of error message items. The items
are delimited by commas. The items that can be
in the list are the words:
1. SHORT ...indicates the short error message
2. EXPLAIN ...the explanation of the short message
3. LONG ...the long error message
4. TRACEBACK ...the traceback
5. ALL ...indicates "output all messages"
6. NONE ...indicates "don't output any messages"
7. DEFAULT ...same as ALL, but includes default
message
A "list" is a character string containing some or
all of the above words, delimited by commas. Examples
are:
1. "SHORT, EXPLAIN"
2. "SHORT, LONG"
3. "ALL"
4. "NONE"
5. "ALL, NONE, ALL, SHORT, NONE"
Each word in the list can be thought of as
"flipping a switch" to enable or disable the output
of the message(s) indicated by the word. The
words are acted on in the order they occur in the
list, starting with the leftmost word. As examples,
consider the sample lists above.
The effect of the first list above, "SHORT, EXPLAIN",
is to enable the output of the short error message
and the explanatory text corresponding to it.
The effect of the second list is to enable the output
of the short and long messages.
The effect of the third list is to enable the output of
all of the error messages (short, long, explanation
of the short message, and traceback).
The effect of the fourth list is to disable output of
all of the messages.
The effect of the fifth list is to disable output of
all of the messages. The reason for this is that
the words in the list are responded to in order,
from left to right, and "NONE" is the last word.
If any words other than SHORT, LONG, EXPLAIN, ALL,
DEFAULT, TRACEBACK or NONE appear in list, those words
that are recognized are responded to. The words
that are not recognized are diagnosed as
erroneous, and error messages are generated
for each such unrecognized word.
The length of list is caller-defined, but only
the first 100 characters of list will be saved
for later retrieval.
Only the first 10 items in the list are used;
the rest are ignored.
list is a list of error message items. The value of
list is that set by the last call to this routine
using the "SET" option. See "Detailed Input"
for a description of the possible values and
meanings of list.
The initial value returned is "DEFAULT".
Only the first 100 characters of list are saved
when the list is set; any additional characters
are truncated. Therefore, the first 100
characters, at most, of the saved value of list
will be returned.
None.
1) If the input argument op does not indicate a valid operation,
the error SPICE(INVALIDOPERATION) will be signaled.
2) If the input argument list does not indicate a valid list of
error message types, the error SPICE(INVALIDLISTITEM) will be
signaled.
3) The error SPICE(EMPTYSTRING) is signalled if the input
string does not contain at least one character, since the
input string cannot be converted to a Fortran-style string
in this case.
4) The error SPICE(NULLPOINTER) is signalled if the input string
pointer is null.
5) The user must pass a value indicating the length of the output
string, when list is an output. If this value is not at least 2,
the error SPICE(STRINGTOOSHORT) is signaled.
Also, this routine is part of the CSPICE error
handling mechanism.
None.
Please read the "required reading"!
This routine is intended to be used in conjunction with
errdev_c, which selects the default output device to which
the error messages selected by this routine will be
output.
Additionally, the error response action must be
something other than "IGNORE" if the error messages
are to be output. Possible choices of the error
response action are "RETURN", "REPORT", "ABORT", "DEFAULT", and
"IGNORE". Use erract_c to set the error response action.
Only the first 100 characters of list are saved.
The default set of error messages that are output is the
set specified by "DEFAULT"; i.e., all of them, including
the "default" message.
1. In this example, we select as the output device
the file, SPUD.DAT, and then select the error
messages to be output. We choose the short
error message and the traceback. Since a
different set of messages may have been selected
previously, we clear the old setting by putting
the word, "NONE", at the beginning of the list.
/.
Set the error output device to SPUD.DAT:
./
errdev_c ( "SET", lenout, "SPUD.DAT" );
/.
Choose error messages:
./
errprt_c ( "SET", lenout, "NONE, SHORT, TRACEBACK" );
2. In this example we are retrieving the error message list.
/.
Declare the output string and its size.
./
#define LENOUT 50
SpiceChar list[ LENOUT ];
errdev_c ( "GET", LENOUT, list );
The device to which the selected error messages will
be written must be selected via errdev_c; otherwise,
messages will be written to the initial default device.
Only the first 100 characters of list are saved.
None.

Bug fix: case of invalid operation keyword is now
diagnosed, as per the Exceptions section of the header.
-CSPICE Version 2.0.0, 09-FEB-1998 (NJB) (EDW)
Input argument op was changed to type ConstSpiceChar *.
Re-implemented routine without dynamically allocated, temporary
strings.
Corrected errors in examples in which the call sequence
was incorrect.
