How to create a std::ofstream to a temp file?

Question

Okay, mkstemp is the preferred way to create a temp file in POSIX.

But it opens the file and returns an int, which is a file descriptor. F

Answer 1

char tempFileName[20]; // name only valid till next invocation of tempFileOpen
ofstream tempFile;
void tempFileOpen()
{
    strcpy(tempFileName, "/tmp/XXXXXX");
    mkstemp(tempFileName);
    tempFile.open(tempFileName);
}

This code works for me with GCC/libstdc++6 4.8.4 and Clang 3.9 as well. Thanks to the other replies as well which were helpful to me.
