He's concerned about virtual file (pipe, FIFO, socket). The patch ( 96d1f423f95d ) has the same problem. fseeko with virtual file can fail too. https://man7.org/linux/man-pages/man3/fseek.3.html ESPIPE The file descriptor underlying stream is not seekable (e.g., it refers to a pipe, FIFO, or socket) Call read_binary_file with virtual file,will log in: "could not seek in file" regards, Ranier Vilela
