| void | setExternalLinkPrefix (const std::string &prefix) |
| setExternalLinkPrefix Let’s say you’ve created an external link in foo.h5 and the external link refers to a path name in file bar.h5. If (by intention or accident) the relative location of foo.h5 and bar.h5 changes, the external link becomes invalid, because the HDF5 library can’t locate the file bar.h5. To deal with a situation like that, you can create a prefix that you’d like to apply to the file names of external links before the library attempts to traverse them. | |

map external binary file to a dataset
| file | path to the file |
| offset | offset in bytes |
| size | is the size of the part that is to be mapped (offset+size=fileSize) leave it as 0 to to map everything starting from the offset size == H5F_UNLIMITED means the external file can be of unlimited size and no more files can be added to the external files list |
