nn::jpeg::CTR::JpegMpDecoder::GetLastSoftwarePointer Member Function

#include <nn/jpeg.h>

const char * GetLastSoftwarePointer() const;

None.

If successful, returns a string pointer to the software name. Even if successful, returns NULL if the number of characters (excluding the terminating 0x00) is 0.
Returns NULL on failure.

Gets a string pointer to the program name of the image that was either decoded or whose EXIF information was extracted immediately previous to this call.

If that processing fails, this function also fails. This function needs image data to get the information. Do not destroy the image data. This information is the information registered in the IFD0 Software tag.

This function fails if the string is not 0-terminated. Use the GetLastSoftwareLength function to get the number of characters in the string.
