I'm writing a straightforward C program on Linux and wish to use an existing library's API which expects data from a file. I must feed it a file name as a const char*. But i have data, just like content of a file, already sitting in a buffer allocated on the heap. There is plenty of RAM and we want high performance. Wanting to avoid...
I'd like to create a named pipe, like the one created by "mkfifo", but one caveat. I want the pipe to be bidirectional. That is, I want process A to write to the fifo, and process B to read from it, and vice-versa. A pipe created by "mkfifo" allows process A to read the data its written to the pipe. Normally I'd use two pipes, but I am t...
How can you create a temporary FIFO (named pipe) in Python? This should work: import tempfile temp_file_name = mktemp() os.mkfifo(temp_file_name) open(temp_file_name, os.O_WRONLY) # ... some process, somewhere, will read it ... However, I'm hesitant because of the big warning in Python Docs 11.6 and potential removal because it's ...
I'm looking to use twisted to control communication across Linux pipes (os.pipe()) and fifos (os.mkfifo()) between a master process and a set of slave processes. While I'm positive tat it's possible to use twisted for these types of file descriptors (after all, twisted is great for tcp sockets which *nix abstracts away as file descriptor...
Hello. Short version (if you can answer the short version it does the job for me, the rest is mainly for the benefit of other people with a similar task): In python in Windows, I want to create 2 file objects, attached to the same file (it doesn't have to be an actual file on the hard-drive), one for reading and one for writing, such t...
