C++ Dev Null Os
Named sockets are UNIX domain sockets constructed with socket and bind POSIX APIs, which may be used for advanced interprocess communication. In particular, they may be used to transport open file descriptors from one running process to another. I was wondering if anyone knew of tutorials for writing c programs for pocket viewer handheld computers. I know these toys are more popular in Europe, but I want to start writing programs for them and can't get started. /akustix-enhancer-vst-download.html. Nohup gedit & /dev/null is POSIX syntax and is the same as: nohup gedit & /dev/null That is run nohup gedit in background and then do a /dev/null redirection without running a command. Nohup gedit & /dev/null is not POSIX syntax and is the csh way to redirect both stdout and stderr to /dev/null.csh doesn't have the 2&1 operator as found in Bourne, so it's the only way csh has to.

bool is_regular_file(std::filesystem::file_status s )noexcept; | (1) | (since C++17) |
bool is_regular_file(conststd::filesystem::path& p ); bool is_regular_file(conststd::filesystem::path& p, std::error_code& ec )noexcept; | (2) | (since C++17) |
Checks if the given file status or path corresponds to a regular file.
[edit]Parameters
| s | - | file status to check |
| p | - | path to examine |
| ec | - | error code to store the error status to |
[edit]Return value
true if the file indicated by p or if the type indicated by s refers to a regular file, false otherwise. The non-throwing overload returns false if an error occurs.
[edit]Exceptions
p as the first path argument and the OS error code as the error code argument. The overload taking a std::error_code& parameter sets it to the OS API error code if an OS API call fails, and executes ec.clear() if no errors occur. Any overload not marked noexcept may throw std::bad_alloc if memory allocation fails.[edit]Notes
The throwing overload is additionally specified to throw std::filesystem::filesystem_error if status(p) would throw.
