PetscViewerHDF5PushGroup

Set the current HDF5 group for output

Synopsis

#include "petscviewerhdf5.h" 
PetscErrorCode  PetscViewerHDF5PushGroup(PetscViewer viewer, const char name[])
Not collective

Input Parameters

viewer - the PetscViewer
name - The group name

Notes

This is designed to mnemonically resemble the Unix cd command. + If name begins with '/', it is interpreted as an absolute path fully replacing current group, otherwise it is taken as relative to the current group. . NULL, empty string, or any sequence of all slashes (e.g. "///") is interpreted as the root group "/". - "." means the current group is pushed again.

Example

Suppose the current group is "/a". + If name is NULL, empty string, or a sequence of all slashes (e.g. "///"), then the new group will be "/". . If name is ".", then the new group will be "/a". . If name is "b", then the new group will be "/a/b". - If name is "/b", then the new group will be "/b".

Developer Notes

The root group "/" is internally stored as NULL.
