nn::jpeg::CTR::JpegMpDecoder::GetLastSoftwareLength Member Function

#include <nn/jpeg.h>

size_t GetLastSoftwareLength() const;

None.

If successful, returns the number of characters in the string (excluding the terminating "). This means that 0 may even be returned as the value when the function succeeds.
Returns 0 on failure.

Gets the number of characters in the software name string of the image that was either decoded or whose EXIF information was extracted immediately previous to this call.

If that previous operation failed, this function also fails. This function needs the image data to get the information. So 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 GetLastSoftwarePointer function to get the string pointer.
