Function in Windows that behaves similarly to mkstemp(char* template)

Question

I am looking for some direction in finding a Windows function that acts similarly to

mkstemp(char*) 

does in Linux, i.e., creates unique filename, opens file, and returns file descriptor. I have come across _mktemp_s, but that only incorporates a small part of what I need. Any suggestions/information in the implementation of a Windows style mkstemp() function would be greatly appreciated.

Answer 1

If WINAPI is permitted then the function GetTempFileName() does almost everything required, with the exception that it does not return a file descriptor. This function could be wrapped in a function to achieve the exact behaviour required.
