PetscBoxUpload - Loads a file to the Box Drive
This routine has not yet been written; it is just copied from Google Drive
Not collective, only the first process in the MPI_Comm uploads the file
Input Parameters:
+ comm - MPI communicator
. access_token - obtained with PetscBoxRefresh(), pass NULL to have PETSc generate one
- filename - file to upload; if you upload multiple times it will have different names each time on Box Drive
Options Database:
. -box_refresh_token XXX
Usage Patterns:
With PETSc option -box_refresh_token XXX given
PetscBoxUpload(comm,NULL,filename); will upload file with no user interaction
Without PETSc option -box_refresh_token XXX given
PetscBoxUpload(comm,NULL,filename); for first use will prompt user to authorize access to Box Drive with their processor
With PETSc option -box_refresh_token XXX given
PetscBoxRefresh(comm,NULL,access_token,sizeof(access_token));
PetscBoxUpload(comm,access_token,filename);
With refresh token entered in some way by the user
PetscBoxRefresh(comm,refresh_token,access_token,sizeof(access_token));
PetscBoxUpload(comm,access_token,filename);
PetscBoxAuthorize(comm,access_token,refresh_token,sizeof(access_token));
