static

Get index range of image files matched by path.

Parameters

pfirst_index	pointer to index updated with the first number in the range
plast_index	pointer to index updated with the last number in the range
path	path which has to be matched by the image files in the range
start_index	minimum accepted value for the first index in the range

Returns: -1 if no image file could be found
