void _Rindara(_RFILE *fp, char *indic_buf);Language Level: ILE C Extension
Threadsafe: No.
Job CCSID Interface: All character data sent to this function is expected to be in the CCSID of the job. All character data returned by this function is in the CCSID of the job. See Understanding CCSIDs and Locales for more information.
Description
The _Rindara() function registers indic_buf as the separate indicator area to be used by the file specified by fp. The file must be opened with the keyword indicators=Y on the _Ropen() function. The DDS for the file should specify also that a separate indicator area is to be used. It is generally best to initialize a separate indicator area explicitly with '0' (character) in each byte.
The _Rindara() function is valid for display, ICF, and printer files.
Return Value
The _Rindara() function returns void. See Table 12 and Table 14 for errno settings.
