0024 /* The GnuPG project consists of many components.  Error codes are
0025  * exchanged between all components.  The common error codes and their
0026  * user-presentable descriptions are kept into a shared library to
0027  * allow adding new error codes and components without recompiling any
0028  * of the other components.  In addition to error codes this library
0029  * also features several other groups of functions which are common to
0030  * all GnuPG components.  They may be used by independet project as
0031  * well.  The interfaces will not change in a backward incompatible way.
0032  *
0033  * An error code together with an error source build up an error
0034  * value.  As the error value is been passed from one component to
0035  * another, it preserves the information about the source and nature
0036  * of the error.
0037  *
0038  * A component of the GnuPG project can define the following macros to
0039  * tune the behaviour of the library:
0040  *
0041  * GPG_ERR_SOURCE_DEFAULT: Define to an error source of type
0042  * gpg_err_source_t to make that source the default for gpg_error().
0043  * Otherwise GPG_ERR_SOURCE_UNKNOWN is used as default.
0044  *
0045  * GPG_ERR_ENABLE_GETTEXT_MACROS: Define to provide macros to map the
0046  * internal gettext API to standard names.  This has only an effect on
0047  * Windows platforms.
0048  *
0049  * GPGRT_ENABLE_ES_MACROS: Define to provide "es_" macros for the
0050  * estream functions.
0051  *
0052  * GPGRT_ENABLE_LOG_MACROS: Define to provide short versions of the
0053  * log functions.
0054  *
0055  * GPGRT_ENABLE_ARGPARSE_MACROS: Needs to be defined to provide the
0056  * mandatory macros of the argparse interface.
