Am I going nuts? The small file enclosed below is the one which is listed
in the online reference (CP Reference). However, when I try to run it,
it says that the environment variable is not found. How can it not find
PATH? I also tried with LIBPATH, DPATH, and others. I'm using CSD 28 (CSet/2)
and GA+SP. Is there some call I need to make before I run this?? I've tried
this with DosScanEnv and DosSearchPath, and with just DosSearchPath with
the proper vector set (I think). I've also tried putting the ENVVARNAME and
FILENAME into regular strings, with no better luck. Any help is appreciated.

#define INCL_DOSFILEMGR
#include <os2.h>
#include <stdio.h>

#define ENVVARNAME   "PATH"       /* Environment variable name */
#define FILENAME     "test.c"    /* File for which to search */

main() {
   PSZ       ResultPointer;         /* Environment scan result
                                        pointer (returned) */
   BYTE      ResultBuffer[128];     /* Path search result
                                        (returned) */
   APIRET    rc;                    /* Return code */

  /** Scan environment segment for PATH; notice the far-string **/
  /**   pointer specification ("%Fs") used to print.           **/

   if(!(rc=DosScanEnv(ENVVARNAME,  /* Environment variable name */
                      ResultPointer)))  /* Scan result pointer
                                            (returned) */
     printf("%s is %Fs\n", ENVVARNAME, ResultPointer);

/* This comes out as 203, environment variable not found */
printf("RC 1 = %d\n", rc);
   /** Search current directory + PATH variable for "test.c"  **/
   if(!(rc=DosSearchPath(SEARCH_CUR_DIRECTORY,    /* Search control
                                                       vector */
                         ENVVARNAME,      /* Search path reference
                                              string */
                         FILENAME,        /* File name string */
                         ResultBuffer,    /* Search result
                                              (returned) */
                       sizeof(ResultBuffer)))) /* Length of search
                                                     result */
     printf("Found desired file -- %s\n", ResultBuffer);

/* This comes out as 2, file not found */
printf("RC 2 = %d\n", rc);
 }
