(moved some stuff to the Talk:Driver page
Found error in DosGetMessage API return codes
Really it is OS/2 API bugreport
/* Some words on how create message files:
This example demonstrates how to create a message with inserts from a system message file. It
creates a file named "SAMPLE.TXT" with the following 3 lines in it:
;sample system message file - SAMPLE.MSG ...
DOS<CR>
DOS1000E: %1 Error at Station %2%0<CR>
Note:<CR> stands for '\n'
Note2:if you write <SPACE><CR> then you will see that MKMSGF is really guano
It then generates a message file by issuing the following command at an OS/2 command prompt:
MKMSGF SAMPLE.TXT SAMPLE.MSG
*/
#define INCL_DOSMISC /* Miscellaneous values */
#define INCL_DOSERRORS /* DOS Error values */
#include <os2.h>
#include <stdio.h>
#include <string.h>
int main(VOID)
{
UCHAR *IvTable[2] = {0}; /* Table of variables to insert */
UCHAR szOutMsg[80]= ""; /* Message buffer */
ULONG ulMsgLen = 0; /* Length of returned message */
APIRET rc = 0; /* Return code */
IvTable[0] = "Automation Failure";
IvTable[1] = "69B";
/* Create error message with inserts from system message file SAMPLE.MSG */
rc = DosGetMessage(IvTable, /* Message insert pointer array */
2, /* Number of inserts */
szOutMsg, /* Output message */
sizeof(szOutMsg), /* Length of output message area */
100L, /* Number of message requested */
"SAMPLE.MSG", /* Message file (created by MKMSGF) */
&ulMsgLen); /* Length of resulting output message */
if (rc != NO_ERROR) {
printf("DosGetMessage error: return code = %u\n", rc);
return 1;
}
printf("%s\n", szOutMsg);
return NO_ERROR;
}
/*--------------- Output will be as ------------- C:>message.exe DosGetMessage error: return code = 316 /*--------------- Output sould be as ------------- DosGetMessage error: return code = 317 -------------------------------------------------*/
/*
DosGetMessage returns one of the following values:
.......
316 ERROR_MR_MSG_TOO_LONG
317 ERROR_MR_MID_NOT_FOUND
