Detailed Description

This template converts a functor for generating file names, into a functor for generating int file descriptors. It may be necessary when a streambuf can only be initialised with a file descriptor, but the calling program can only create a temporary file name.

Member Function Documentation

void rpa::filgen_name_to_fd_base::close

(

const char *

filNam

)

The file itself is not removed by this class. It is only closed. It is up to the base class to remove it.

void rpa::filgen_name_to_fd_base::open

(

const char *

filNam

)

For security reasons, only this process can access this file.

If the file already exists, we do not truncate it, but try to reuse the allocated disk space : It may be unfragmented, which is good.

If O_CREAT and O_EXCL are set, fails if the file exists

int rpa::filgen_name_to_fd_base::operator()

(

void

)

const [inline]

This method is used by the constructor of a stream file buffer. It must be 'const', and always return the same value.
