The function dc_ist_write() outputs a record in a specified range to an internode shared table. If multiple records are collectively specified and an error occurs with any of the specified records, the function dc_ist_write() returns with an error without outputting the records to the output buffer.

When the function dc_ist_write() terminates normally, the contents of the record at the local node are updated. The contents of internode shared tables at other nodes are updated with a certain time interval after this function returns normally.

When outputting an internode shared table record, specify the table descriptor which is the return value of the function dc_ist_open().

istid

Specify the table descriptor of the internode shared table to be accessed.

keyptr

Specify the address of the structure (IST key) indicating the range of the relative record numbers of the record to be output. For the structure, specify the record range with the first and last relative block numbers. The structure formats are as follows:

struct  DC_ISTKEY {
                   int  fstrecno;
                   int  endrecno;
                   };

• fstrecno
  Specify the first relative record number of the record to be accessed.
  
• endrecno
  Specify the last relative record number of the record to be accessed. If 0 is specified, only the record with the relative record number specified with fstrecno is input.
  

keyno

Specify the number of structures (number of arrays in the structure) to be specified for keyptr.

bufadr

Specify the address of the buffer containing update data to be output.

bufsize

Specify the output buffer length. The value must be (output record length x number of output records).

flags

Specify DCNOFLAGS.
