PetscGetRealPath
Get the path without symbolic links etc. and in absolute form.
Synopsis
PetscErrorCode PetscGetRealPath(const char path[],char rpath[])
Not Collective
Input Parameter
path -path to resolve
Output Parameter
rpath -resolved path
Notes
rpath is assumed to be of length PETSC_MAX_PATH_LEN.
Systems that use the automounter often generate absolute paths
of the form "/tmp_mnt....". However, the automounter will fail to
mount this path if it is not already mounted, so we remove this from
the head of the line. This may cause problems if, for some reason,
/tmp_mnt is valid and not the result of the automounter.
