• psOptions -- the options struct returned by GDALMultiDimTranslateOptionsNew() or NULL.

• pbUsageError -- pointer to a integer output variable to store if any usage error has occurred or NULL.

戻り値:

the output dataset (new dataset that must be closed using GDALClose(), or hDstDS is not NULL) or NULL in case of error.

GDALVectorInfoOptions *GDALVectorInfoOptionsNew(char **papszArgv, GDALVectorInfoOptionsForBinary *psOptionsForBinary)

Allocates a GDALVectorInfoOptions struct.

Note that when this function is used a library function, and not from the ogrinfo utility, a dataset name must be specified if any layer names(s) are specified (if no layer name is specific, passing a dataset name is not needed). That dataset name may be a dummy one, as the dataset taken into account is the hDS parameter passed to GDALVectorInfo(). Similarly the -oo switch in a non-ogrinfo context will be ignored, and it is the responsibility of the user to apply them when opening the hDS parameter passed to GDALVectorInfo().

GDAL 3.7

パラメータ:

• papszArgv -- NULL terminated list of options (potentially including filename and open options too), or NULL. The accepted options are the ones of the ogrinfo utility.

• psOptionsForBinary -- (output) may be NULL (and should generally be NULL), otherwise (ogrinfo_bin.cpp use case) must be allocated with GDALVectorInfoOptionsForBinaryNew() prior to this function. Will be filled with potentially present filename, open options, subdataset number...

戻り値:

pointer to the allocated GDALVectorInfoOptions struct. Must be freed with GDALVectorInfoOptionsFree().

void GDALVectorInfoOptionsFree(GDALVectorInfoOptions *psOptions)

Frees the GDALVectorInfoOptions struct.

パラメータ:

psOptions -- the options struct for GDALVectorInfo().

char *GDALVectorInfo(GDALDatasetH hDataset, const GDALVectorInfoOptions *psOptions)

Lists various information about a GDAL supported vector dataset.

This is the equivalent of the ogrinfo utility.

GDALVectorInfoOptions* must be allocated and freed with GDALVectorInfoOptionsNew() and GDALVectorInfoOptionsFree() respectively.

GDAL 3.7

パラメータ:

• hDataset -- the dataset handle.

• psOptions -- the options structure returned by GDALVectorInfoOptionsNew() or NULL.

戻り値:

string corresponding to the information about the raster dataset (must be freed with CPLFree()), or NULL in case of error.

GDALTileIndexOptions *GDALTileIndexOptionsNew(char **papszArgv, GDALTileIndexOptionsForBinary *psOptionsForBinary)

Allocates a GDALTileIndexOptions struct.

psOptions -- the options struct for GDALTileIndex().

GDALDatasetH GDALTileIndex(const char *pszDest, int nSrcCount, const char *const *papszSrcDSNames, const GDALTileIndexOptions *psOptions, int *pbUsageError)

Build a tile index from a list of datasets.

This is the equivalent of the gdaltindex utility.

GDALTileIndexOptions* must be allocated and freed with GDALTileIndexOptionsNew() and GDALTileIndexOptionsFree() respectively.

Since

GDAL3.9

パラメータ:

• pszDest -- the destination dataset path.

• papszSrcDSNames -- the list of input dataset names

• psOptionsIn -- the options struct returned by GDALTileIndexOptionsNew() or NULL.

• pbUsageError -- pointer to a integer output variable to store if any usage error has occurred.

戻り値:

the output dataset (new dataset that must be closed using GDALClose()) or NULL in case of error.
