knows a number of generic, standardized error names, that are

<para>In addition to this list, in sd-bus the special error

to D-Bus errors and back. For example, the error

<constant>EUCLEAN</constant> is mapped to

<literal>System.Error.EUCLEAN</literal> and back.</para>

fields are unsuitable for authorization decisions as they may be

<title>Description</title>
|

|

<para>The <structname>sd_bus_error</structname> structure carries
|
||||
information for a <filename>sd-bus</filename> error. The
|
||||
functions described below can be used to set and query fields in
|
||||
this structure. The <structfield>name</structfield> field contains a
|
||||
short identifier of an error. It should follow the rules for error
|
||||
names described in the D-Bus specification, subsection <ulink
|
||||
information about a D-Bus error condition. The functions described
|
||||
below may be used to set and query fields in this structure. The
|
||||
<structfield>name</structfield> field contains a short identifier
|
||||
of an error. It should follow the rules for error names described
|
||||
in the D-Bus specification, subsection <ulink
|
||||
url="http://dbus.freedesktop.org/doc/dbus-specification.html#message-protocol-names">Valid
|
||||
Names</ulink>. The <structfield>message</structfield> is a human
|
||||
readable string describing the details. When no longer necessary,
|
||||
resources held by this structure should be destroyed with
|
||||
<function>sd_bus_error_free</function>.</para>
|
||||
Names</ulink>. A number of common, standardized error names are
|
||||
described in
|
||||
<citerefentry><refentrytitle>sd-bus-errors</refentrytitle><manvolnum>3</manvolnum></citerefentry>,
|
||||
but additional domain-specific errors may be defined by
|
||||
applications. The <structfield>message</structfield> field usually
|
||||
contains a human readable string describing the details, but might
|
||||
be NULL. An unset <structname>sd_bus_error</structname> structure
|
||||
should have both fields initialized to NULL. Set an error
|
||||
structure to <constant>SD_BUS_ERROR_NULL</constant> in order to
|
||||
reset both fields to NULL. When no longer necessary, resources
|
||||
held by the <structname>sd_bus_error</structname>structure should
|
||||
be destroyed with <function>sd_bus_error_free()</function>.</para>
|
||||
|
||||
<para><function>sd_bus_error_set</function> will return an
|
||||
errno-like negative value returned based on parameter
|
||||
<parameter>name</parameter> (see
|
||||
<citerefentry project='man-pages'><refentrytitle>errno</refentrytitle><manvolnum>3</manvolnum></citerefentry>).
|
||||
Various well-known D-Bus errors are converted to specific values,
|
||||
and the remaining ones to <constant>-ENXIO</constant>. Well-known
|
||||
D-Bus error names are available as constants
|
||||
<constant>SD_BUS_ERROR_FAILED</constant>, etc., listed above. If
|
||||
<para><function>sd_bus_error_set()</function> sets an error
|
||||
structure to the specified name and message strings. The strings
|
||||
will be copied into internal, newly allocated memory. It is
|
||||
essential to free the error structure again when it is not
|
||||
required anymore (see above). The function will return an
|
||||
<varname>errno</varname>-like negative value (see <citerefentry
|
||||
project='man-pages'><refentrytitle>errno</refentrytitle><manvolnum>3</manvolnum></citerefentry>)
|
||||
determined from the specified error name. Various well-known
|
||||
D-Bus errors are converted to well-known <varname>errno</varname>
|
||||
counterparts, and the other ones to <constant>-EIO</constant>. See
|
||||
<citerefentry><refentrytitle>sd-bus-errors</refentrytitle><manvolnum>3</manvolnum></citerefentry>
|
||||
for a list of well-known error names. Additional error mappings
|
||||
may be defined with
|
||||
<citerefentry><refentrytitle>sd_bus_error_add_map</refentrytitle><manvolnum>3</manvolnum></citerefentry>. If
|
||||
<parameter>e</parameter> is NULL no error structure is initialized
|
||||
but the error is still converted into an
|
||||
<varname>errno</varname>-style error. If
|
||||
<parameter>name</parameter> is <constant>NULL</constant>, it is
|
||||
assumed that no error occurred, and 0 is returned. This means that
|
||||
this function may be conveniently used in a
|
||||
<function>return</function> statement.</para>
|
||||
<function>return</function> statement. If
|
||||
<parameter>message</parameter> is NULL no message is set. This
|
||||
call can fail if no memory may be allocated for the name and
|
||||
message strings, in which case an
|
||||
<constant>SD_BUS_ERROR_NO_MEMORY</constant> error might be set
|
||||
instead and -ENOMEM returned. Do not use this call on error
|
||||
structures that are already initialized. If you intend to reuse an
|

error structure free the old data stored in it with
|

<function>sd_bus_error_free()</function> first.</para>

<structfield>message</structfield> in the

<structname>sd_bus_error</structname> structure
|
||||
<parameter>e</parameter> points at will be filled in. As described above,
|
||||
<parameter>name</parameter> may be <constant>NULL</constant>,
|

which is treated as no error. Parameter
|

<parameter>message</parameter> may also be

<constant>NULL</constant>, in which case no message is specified.

this call does not allocate memory it will not fail with an

out-of-memory condition, as

<function>sd_bus_error_set()</function> can, as described

above. Alternatively, the

on-the-fly.</para>

convenient usage in <function>return</function> statements. This

<title>Description</title>
|
||||
|
||||
<para>The <function>sd_bus_error_add_map()</function> call may be
|
||||
used to register additional mappings for converting D-Bus errors
|
||||
to Linux <varname>errno</varname>-style errors. The mappings
|
||||
defined with this call are consulted by calls such as
|
||||
<citerefentry><refentrytitle>sd_bus_error_set</refentrytitle><manvolnum>3</manvolnum></citerefentry>
|
||||
or
|
||||
<citerefentry><refentrytitle>sd_bus_error_get_errno</refentrytitle><manvolnum>3</manvolnum></citerefentry>. By
|
||||
default a number of generic, standardized mappings are known, as
|
||||
documented in
|
||||
<citerefentry><refentrytitle>sd-bus-errors</refentrytitle><manvolnum>3</manvolnum></citerefentry>. Use
|
||||
this call to add further, application-specific mappings.</para>
|
||||
|
||||
<para>The function takes a pointer to an array of
|
||||
<structname>sd_bus_error_map</structname> structures. A reference
|
||||
to the specified array is added to the lookup tables for error
|
||||
mappings. Note that the structure is not copied, it is hence
|
||||
essential that the array stays available and constant during the
|
||||
entire remaining runtime of the process.</para>
|
||||
|
||||
<para>The mapping array should be put together with a series of
|
||||
<constant>SD_BUS_ERROR_MAP()</constant> macro invocations, that
|
||||
take a literal name string and a (positive)
|
||||
<varname>errno</varname>-style error number. The last entry of the
|
||||
array should be an invocation of the
|
||||
<constant>SD_BUS_ERROR_MAP_END</constant> macro. The array should not be
|
||||
put together without use of these two macros.</para>
|
||||
|
||||
<para>Note that the call is idempotent: it is safe to invoke it
|
||||
multiple times with the parameter, which will only add the passed
|
||||
mapping array once.</para>
|
||||
|
||||
<para>Note that the memory allocated by this call is not intended
|
||||
to be freed during the lifetime of the process. It should not be
|
||||
freed explicitly.</para>

before. On error, a negative <varname>errno</varname>-style error
|

code is returned. See below for known error codes.</para>
