Problems with file system functions

Question

I've been using CLibInit.supplyFile( ); to feed files to the
C code to work with. My code looks like:
//in Flash:
cLibInit.supplyFile("./myfile", _myFileByteArray);
if ( !access (file, R_OK) )
// later:
if ( (handle = open (file,O_RDONLY ) == -1)
printf (" couldn't open %s\n",file);
return;
The access test passes, signalling that the file exists and
everything is well. BUT, the open fails with a "File or directory
does not exist" error.
I tinkered around some, and noticed that the open() works
when I removed the access() call. Similarly, if I put the open in
front of the acess, the open succeeds, but the access fails. This
makes me think that supplyFile might be "one use," meaning that the
library 'forgets' the file once a system call accesses it. Is that
the case? If so, it's truly bizarre functionality! But it's very
possible that I'm missing some nuance of the UNIX system libs...
:)

Is it possible to open file in C?
I tried to open file but it makes error "Can not Open File "
// in fileread.c
static AS3_Val fileread2(void* self, AS3_Val args)
char* val = NULL;
AS3_ArrayValue( args, "StrType", &val );
char result[256];
FILE *fp1;
char s[256];
if((fp1=fopen(val,"r"))==NULL)
sprintf(result,"Can not Open File : %s", val);
return AS3_String(result);
while(fgets(s,256,fp1)!=NULL) {
sprintf(result,"_%s",s);
fclose(fp1);
return AS3_String(result);
int main() {
AS3_Val fileread2Val = AS3_Function( NULL, fileread2 );
AS3_Val result = AS3_Object( "fileread2: AS3ValType",
fileread2Val );
AS3_Release( fileread2Val );
AS3_LibInit( result );
return 0;
// In fileread.as
import cmodule.fileread2.CLibInit;
private function init():void
var loader:CLibInit = new CLibInit;
var lib:Object = loader.init();
//trace(lib.fileread2("_ReadMe.txt"));
var arr:ByteArray = new ByteArray();
loader.supplyFile("_ReadMe.txt", arr);
trace("Array : " + arr);
}
