/**********************************************************************
* AVCE00WriteOpen()
*
* Open (create) an Arc/Info coverage, ready to be receive a stream
* of ASCII E00 lines and convert that to the binary coverage format.
*
* For now, writing to or overwriting existing coverages is not supported
* (and may quite well never be!)... you can only create new coverages.
*
* Important Note: The E00 source lines are assumed to be valid... the
* library performs no validation on the consistency of what it is
* given as input (i.e. topology, polygons consistency, etc.).
* So the coverage that will be created will be only as good as the
* E00 input that is used to generate it.
*
* pszCoverPath MUST be the name of the coverage directory, including
* the path to it.
* (contrary to AVCE00ReadOpen(), you cannot pass the name of one of
* the files in the coverage directory).
* The name of the coverage MUST be included in pszCoverPath... this
* means that passing "." is invalid.
*
* nPrecision should always be AVC_DEFAULT_PREC to automagically detect the
* source coverage's precision and use that same precision
* for the new coverage.
*
* This parameter has been included to allow adding the
* possibility to eventually create coverages with a precision
* different from the source E00.
* Given the way the lib is built, it could be possible to
* also pass AVC_SINGLE_PREC or AVC_DOUBLE_PREC to explicitly
* request the creation of a coverage with that precision,
* but the library does not (not yet!) properly convert the
* TABLE attributes' precision, and the resulting coverage may
* be invalid in some cases.
* This improvement is on the ToDo list!
*
* Returns a new AVCE00WritePtr handle or NULL if the coverage could
* not be created or if a coverage with that name already exists.
*
* The handle will eventually have to be released with AVCE00ReadClose().
