Two methods for generating temporary files in linux: general Linux technology-Linux programming and kernel information. From "Advanced Linux Programming" By Mark Mitchell, Jeffrey Oldham, Alex Samuel.
There are two methods:
1) Use mkstemp. When using this function, the file name must have a naming template ending with six X, for example, char temp_filename [] = "/tmp/temp_file.XXXXXX ". Using this method, temporary files are not automatically deleted. You can call unlink () to reduce the reference count by one, so that the file is automatically deleted when the program is launched.
2) use tmpfile (). This function has been unlinked internally, so you do not need to explicitly subtract one counter.
Note: There are also mktemp, tmpnam and tempnam. But it is not recommended for reliability and security.
