strerror()Prototype: char *strerror(int errnum);Header File: string.h (C) or cstring (C++) Explanation: Strerror returns a pointer to a string that contains the identification for an error-number. This is usually used with a function that returns an error number based on the result of an operation. It is a very bad idea to start modifying the string it returns. //Example prints out error number 2 #include <iostream> #include <cstring> using namespace std; int main() { cout<<strerror(2); }Other Functions |
