◆ buffer
| struct wmulti_buffer file_desc_t::buffer |
The wmulti_buffer is used to aggregate multiple variables with the same communication pattern prior to a write.
◆ do_io
| int file_desc_t::do_io |
True if this task should participate in IO (only true for one task with netcdf serial files.
◆ fh
| int file_desc_t::fh |
The ncid returned for this file by the underlying library (netcdf or pnetcdf).
◆ fname
| char file_desc_t::fname[PIO_MAX_NAME+1] |
◆ io_fstats
| struct spio_io_fstats_summary* file_desc_t::io_fstats |
I/O statistics associated with this file.
◆ iosystem
| iosystem_desc_t* file_desc_t::iosystem |
The IO system ID used to open this file.
◆ iotype
| int file_desc_t::iotype |
The PIO_TYPE value that was used to open this file.
◆ is_reopened
| bool file_desc_t::is_reopened |
True if this is an existing file reopened.
◆ mode
| int file_desc_t::mode |
Mode used when file was opened.
◆ mvcache
| void* file_desc_t::mvcache |
Data buffer per IO decomposition for this file.
Cache for storing data corresponding to multiple variables binned on the I/O decomposition used by the variable
◆ next
| struct file_desc_t* file_desc_t::next |
Pointer to the next file_desc_t in the list of open files.
◆ num_unlim_dimids
| int file_desc_t::num_unlim_dimids |

◆ rb_pend
| PIO_Offset file_desc_t::rb_pend |
◆ reserve_extra_header_space
| bool file_desc_t::reserve_extra_header_space |
True if we need reserve some extra space in the header when creating NetCDF files to accommodate anticipated changes.
◆ unlim_dimids
| int* file_desc_t::unlim_dimids |
◆ varlist
| struct var_desc_t file_desc_t::varlist[PIO_MAX_VARS] |
List of variables in this file (deprecated).
