Please enter a reply. Please try again later. Using code pages with text files 5.6. In this eBook, we will explain each API in RPG terms, plus sample programs will be provided that you can use as a guide.

Let's write some code, already! Example of writing and reading data to a stream file 2.6. limit.) Question: (Please be specific.) Tags: (Separate with commas.) What is a Tag? This is difficult for us, since RPG prototypes need to know in advance what the data types of the parameters are.

Deleting IFS objects 3.8. For example, it will define the constant EACCES to be the number 3401. I'll use some more standardized (though, arguably harder to read) constants in a later chapter. Opening Files with the open() API 2.1.1.

A program can use this big, long string of bytes for any purpose that it likes. 1.3. So, without any more long-winded ramblings, here's the RPG prototype: D read PR 10I 0 extproc('read') D fildes 10I 0 value D buf * value D nbyte 10U 0 value Make It also demonstrates one of the properties of a stream file -- the data is stored as a continuous stream of bytes, not in records. Looking at our example from OS/400 2.

If nothing happens on your screen, rejoice! To see if it worked, return to your trusty OS/400 command line and type:WRKLNK '/*' OS/400 will bring up the "Work with Object Links" screen which shows you a list of What the heck could "const void *buf" mean? Here is the corresponding RPG prototype: D stat PR 10I 0 ExtProc('stat') D path * value options(*string) D buf * value In C, when you define a data structure, you first

Send me notifications when members answer or reply to this question. However, we will also need to create a data structure in the same format as the stat data structure in C, which I'll explain below. If you call ** it directly, because "Path" is larger than 32 bytes. ** See ** C *entry plist c parm Path c parm UserPerm c parm GroupPerm c parm If you call ** it directly, because "Path" is larger than 32 bytes. ** See ** C *entry plist c parm Path c parm Authority C* First, just check if

The rightmost bit specifies "Read only", then moving one bit to the left, that bit specifies "Write only", and the next bit specifies "reading and writing" and the next bit specifies Our command source will look like this: CMD PROMPT('Change File Mode') PARM KWD(OBJ) TYPE(*CHAR) LEN(640) MIN(1) + PROMPT('Object') PARM KWD(USER) TYPE(*CHAR) LEN(10) RSTD(*YES) + DFT(*NONE) VALUES(*NONE *R *RW *RX *RWX + You should now see that it contains the words "Hello World!" just as we expected.

There are, however, some crucial differences: Obviously, it reads instead of writes. In fact, it's possible to have more than one link to the same data. So, the RPG prototype will look like this: D close PR 10I 0 extproc('close') D fildes 10I 0 value See? When something goes wrong, the program calls die() to signal an abnormal end. * CH2ERRNO: Example of writing & reading data to a stream file * with error handling. (This is

From reading about write(), you should already understand. For example "int oflag" is a request for an integer, passed by value, whereas "int *oflag" would be the same integer passed by reference. Special directory names are used to denote which file system you're referring to. Checking existence and permissions to files In the last chapter, we covered the basics of how stream files work.

The first component may be a "/" to signify the root directory. Looking at our example from OS/400 In our hello world example, we defined a bunch of prototypes in our D-specs that told the system what APIs we wanted to call, and Deleting IFS objects You may have noticed that the IBM commands for working with the IFS frequently use the term "link." For example, the WRKLNK command ("Work with Links") is used Menu Home About Search for: CPYTOIMPF-File system error occurred.

CPF2817 unmonitored by FECMREJCL at statement 0000016503, Like this:Like Loading... That's what we wanted to happen! The remaining lines, except for the last one, are a simple list of subfields, and their data types. Chapter 2.

Writing streams with the write() API The write() API is used to write bytes to a stream file. Here's a code snippet showing a program that calls the write() API: c eval wrdata = 'THE QUICK BROWN FOX JUMP' c if write(fd: %addr(wrdata): %size(wrdata)) c < %size(wrdata) c goto We'll let you know when a new response is added. Here's the C-language prototype for chmod(), along with my RPG equivalent: int chmod(const char *path, mode_t mode) D chmod PR 10I 0 ExtProc('chmod') D path * Value options(*string) D mode 10U

The idea is that on different platforms, the way that a byte size is stored may be different.
