std::strerror

| Defined in header <cstring>

| char* strerror( int errnum ); |
||
Returns text version of the error code errnum. errnum is usually acquired from the errno variable, however the function accepts any value of type int. The message is locale-specific.
The returned byte string must not be modified by the program, but may be overwritten by a subsequent call to the strerror function.
