File Operations

Create a file.
NC_create(const char *name, int mode, size_t initialsz, int basepe,

size_t *chunksizehintp, int useparallel, void *parameters, int *ncidp)
Create a file for parallel I/O.
nc_create_par(const char *name, int mode, MPI_Comm comm, MPI_Info info, int* ncidp)
Open an existing file.
NC_open(const char *name, int mode, int basepe, size_t *chunksizehintp,

int useparallel, void *parameters, int *ncidp)
Open an existing file for parallel I/O.
nc_open_par(const char *name, int mode, MPI_Comm comm, MPI_Info info, int* ncidp)
Close an opened file.
nc_close(int ncid)
Enter the define mode.
nc_redef(int ncid)
End the define mode.
nc_enddef(int ncid)
