16  * Various things (like EXTERNL) are defined in netcdf.h
17  * to make them available for use by the netcdf_XXX.h files.

EXTERNL int nc_open_par(const char *path, int mode, MPI_Comm comm, MPI_Info info, int *ncidp)
Open an existing netCDF file for parallel I/O.
Definition: dparallel.c:208
EXTERNL int nc_create_par(const char *path, int cmode, MPI_Comm comm, MPI_Info info, int *ncidp)
Create a netCDF file for parallel I/O.
Definition: dparallel.c:100
EXTERNL int nc_var_par_access(int ncid, int varid, int par_access)
This function will change the parallel access of a variable from independent to collective and vice v...
Definition: dparallel.c:381
EXTERNL int nc_open_par_fortran(const char *path, int mode, int comm, int info, int *ncidp)
This is the same as nc_open_par(), but accepts the MPI comm/info as integers.
Definition: dparallel.c:261
EXTERNL int nc_create_par_fortran(const char *path, int cmode, int comm, int info, int *ncidp)
Create a netCDF file for parallel access from the Fortran API.
Definition: dparallel.c:438
#define EXTERNL
Needed for DLL build.
