Dev C++ Working Directory
- Find answers to C Get Current Directory Without Exe from the expert community at Experts Exchange.
- Jun 27, 2010 Dev-C's C compilation settings do not include the C backward compatibility directory (for obvious reasons), and, and even if it did the iostream.h header file would not compile as C code. If you are writing C code, name your file with the.cpp extension.
- May 21, 2017 First of all, Dev C is not a compiler, it's an IDE that interfaces with a compiler (most presumably GCC/MingW in your case). The compiler suite is the one having the header files, not the IDE. Just do code#include /codeinstead of c.
- Apr 25, 2014 The directory at the end of the active path is called the current directory; it is the directory in which the active application started, unless it has been explicitly changed. An application can determine which directory is current by calling the GetCurrentDirectory function.

Returns or changes the current path.

1-2) Returns the absolute path of the current working directory, obtained as if (in native format) by POSIX getcwd. (2) returns path() if error occurs.
3-4) Changes the current working directory to
p, as if by POSIX chdir.[edit]Parameters
| p | - | path to change the current working directory to |
| ec | - | out-parameter for error reporting in the non-throwing overloads |
[edit]Return value
1-2) Returns the current working directory.

1-2) The overload that does not take a std::error_code& parameter throws filesystem_error on underlying OS API errors, constructed with 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.3-4) The overload that does not take a std::error_code& parameter throws filesystem_error on underlying OS API errors, constructed with
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 current working directory is the directory, associated with the process, that is used as the starting location in pathname resolution for relative paths. Traktor scratch duo upgrade to pro 2.
The current path as returned by many operating systems is a dangerous global variable. It may be changed unexpectedly by third-party or system library functions, or by another thread.
