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

*
* IF EXCEPT is not NULL, it is expected to be an ordered list of file
* descriptors, terminated by an entry with the value (-1). These
* file descriptors won't be closed before spawning a new program.
*
* Returns 0 on success or an error code. Calling gpgrt_wait_process
* and gpgrt_release_process is required if the function succeeded.
*
* FLAGS is a bit vector:
*
* GPGRT_SPAWN_NONBLOCK
* If set the two output streams are created in non-blocking
* mode and the input stream is switched to non-blocking mode.
* This is merely a convenience feature because the caller
* could do the same with gpgrt_set_nonblock. Does not yet
* work for Windows.
*
* GPGRT_SPAWN_DETACHED
* If set the process will be started as a background process.
* This flag is only useful under W32 systems, so that no new
* console is created and pops up a console window when starting
* the server.
*
* GPGRT_SPAWN_RUN_ASFW
* On W32 run AllowSetForegroundWindow for the child. Note that
* due to unknown problems this actually allows
* SetForegroundWindow for all children of this process.
*
* GNUPG_SPAWN_KEEP_STDIN
* GNUPG_SPAWN_KEEP_STDOUT
* GNUPG_SPAWN_KEEP_STDERR
* Do not assign /dev/null to a non-required standard file
* descriptor.
