1.5.18 ( 0.132/4/2 ) - ioperm - OpenSCManager failed

[pppd]

Hello guys,

       I'd like to use ioperm functions under Cygwin 1.5.18 ( 0.132/4/2 ).

First I have tried to compile my C code ( below ) on Cygwin.

P.S: It works on Linux.

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <sys/io.h>

int main( void ) {

unsigned char Value;

    ioperm(0x378, 3, 1);
    Value = inb(0x378+1);
    ioperm(0x378, 3, 0);

    printf("Status Parallel Port -> 0x%x\n", Value );

	return 0;

}

Trying compile...
$ gcc -o io io.c -Wall
/cygdrive/c/DOCUME~1/t00707/CONFIG~1/Temp/ccKOfTff.o:io.c:(.text+0x42): undefined reference to `_ioperm'
/cygdrive/c/DOCUME~1/t00707/CONFIG~1/Temp/ccKOfTff.o:io.c:(.text+0x6d): undefined reference to `_ioperm'
collect2: ld returned 1 exit status

Maybe I need install ioperm package? I have tried it too.

$ ioperm -i
OpenSCManager function call failed.
Error: ioperm.sys installation failed.

and then..

$ ioperm.sys
bash: /usr/bin/ioperm.sys: Permission denied

Does anybody can help me ?

Best Regards,
Douglas Schilling Landgraf
