Using madvise(3C)

[Kishore Kumar Pusukuri]

Hi,
I am trying to play with madvise on my AMD machine running OpenSolaris.2009.06. However, getting the following error when I used to compile the below program with /usr/sfw/bin/g++. Please help me to resolve this.

457: error: `madvise' undeclared (first use this function)
457: error: (Each undeclared identifier is reported only once for each function it appears in.)

Program
=========
....
#include <sys/types.h>
#include <sys/mman.h>
...
...

int
main (void)
{
....

int size = numOptions*sizeof(OptionData);
data = (OptionData*)malloc(size);

if (data == NULL) {
perror("Fatal Error: malloc failed");
exit(-1);
}

int ret = madvise(data, size, MADV_ACCESS_MANY);
if (ret == -1) {
perror("Fatal Error: madvise failed");
exit(-2);
}
...
...

return 0;
}

I see your multiple postings to this list. Only one posting was
necessary.

You did not describe how you are executing g++ but perhaps you have
passed a compiler argument which causes it to request only strict ANSI
C++, which lacks most Unix functions.
