Specifying a CCSID when creating a file with Open() in RPG

List,

 

I am currently developing an application that generates stream files in
various folders in the IFS.

 

To create the file I'm using the open() access API.

 

This API takes the following parameters:

 

int path

int oflag

int mode 

int conversion ID (optional)

int text file creation conversion ID (optional)

 

Now, the problem I have is that I don't know what values to set the various
components of oflag.

 

For example, depending on whether I use O_CCSID or O_CODEPAGE, the value I
pass in conversion ID will either be interpreted as a CCSID value or a
codepage value. This API is a c function so the values will be included in a
header file somewhere, I just don't know what values they should be.

 

I understand which values to include when I use this API, form reading the
API documentation. I simply need to define the values in my procedure
interface in my D-specs. Does anybody know what the values should be? The
list is found below:

One of the following values must be specified in oflag:

O_RDONLY 

O_WRONLY 

O_RDWR 

One or more of the following also can be specified in oflag:

O_APPEND 

O_CREAT 

O_EXCL 

O_LARGEFILE 

O_TRUNC 

O_TEXTDATA 

O_CCSID 

O_CODEPAGE 

O_TEXT_CREAT 

O_INHERITMODE 

O_NONBLOCK 

O_SYNC 

O_DSYNC 

O_RSYNC 

O_SHARE_RDONLY 

O_SHARE_WRONLY 

O_SHARE_RDWR 

O_SHARE_NONE 

All other bits in oflag must be cleared (not set).

Cheers
