## Typedef Documentation

## ◆ GDALDatasetUniquePtr

using GDALDatasetUniquePtr = std::unique_ptr<GDALDataset, GDALDatasetUniquePtrDeleter>

Unique pointer type for GDALDataset.

Appropriate for use on datasets open in non-shared mode and onto which reference counter has not been manually modified.

Since
  GDAL 2.3

## Enumeration Type Documentation

## ◆ GDALIdentifyEnum

enum GDALIdentifyEnum

Enumeration used by GDALDriver::pfnIdentify().

Since
  GDAL 2.1

Enumerator
GDAL_IDENTIFY_UNKNOWN | Identify could not determine if the file is recognized or not by the probed driver.
GDAL_IDENTIFY_FALSE | Identify determined the file is not recognized by the probed driver.
GDAL_IDENTIFY_TRUE | Identify determined the file is recognized by the probed driver.

## ◆ GDALMaskValueRange

enum GDALMaskValueRange

Range of values found in a mask band.

Enumerator
GMVR_0_AND_1_ONLY | Unknown (can also be used for any values between 0 and 255 for a Byte band)
GMVR_0_AND_255_ONLY | Only 0 and 1

## Function Documentation

## ◆ GetGDALDriverManager()

GDALDriverManager* GetGDALDriverManager | ( |  | ) |

Fetch the global GDAL driver manager.

This function fetches the pointer to the singleton global driver manager. If the driver manager doesn't exist it is automatically created.

Returns
  pointer to the global driver manager. This should not be able to fail.
