Probably not; no way to say without seeing your code.
In C, I get no errors at all on a quick test program (at bottom of
message). I tried it on both NFS and non-NFS filesystems. I don't
know what problems you were referring to.
================================================================
#include <stdio.h>
#include <unistd.h>
#include <errno.h>
int main(void)
{
char pattern[100] = "foo.bar.XXXX";
char text[] = "hello world\n";
int i,j;
i = mkstemp(pattern);
printf("pattern now %s\n",pattern);
j = write(i,text,sizeof(text));
if (sizeof(text) != j)
printf("write() wrote wrong length %d\n");
j = close(i);
if (j != 0)
printf("close() returned error; errno is %d\n",errno);
}
