List Of Error Messages In C
Contents |
In C programming language, there is no direct support for error handling. You have to detect the failure and linux errno codes handle the error. In C programming language, return values represents success linux errno example or failure. Inside a C program, when a function fails, you should handle the errors accordingly, or errno.h in c at least record the errors in a log file. When you are running some program on Linux environment, you might notice that it gives some error number. For example, c programming error codes "Error no is : 17", which doesn't really say much. You really need to know what error number 17 means. This article shows all available error numbers along with it descriptions. This article might be a handy reference for you, when you encounter an error number and you would like to know what it means. In C programming
Errno C++
language, there is an external variable called "errno". From this errno variable you can use some error handling functions to find out the error description and handle it appropriately. You have to include errno.h header file to use external variable errno. perror function prints error description in standard error. The strerror function returns a string describing the error code passed in the argument errnum. The following C code snippet tries to open a file through open system call. There are two flags in the open call. O_CREAT flag is to create a file, if the file does not exist. O_EXCL flag is used with O_CREAT, if the file is already exist open call will fail with the proper error number. $ cat fileopen.c #include
the currently compiled class doesn't have the same MOM (Microsoft Object Model) related flags set as its direct parent. This compiler error message is deprecated. E2525: You must define _PCH_STATIC_CONST before including xstring to use this
How To Use Errno
feature You attempted to use a feature defined in xstring, part of the Dinkumware linux error codes 127 standard C++ library. The C++ compiler could not generate a precompiled header because there is a constant (defined in xstring) in the errno to string header. If you want to include xstring, you should first set the define _PCH_STATIC_CONST. E2526: Property 'name' uses another property as getter/setter; Not allowed Properties typically have both a getter and a setter, but a property http://www.thegeekstuff.com/2010/10/linux-error-codes/ cannot serve as either the getter or setter of another property. E2008: Published property access functions must use __fastcall calling convention The calling convention for access functions of a property (read, write, and stored) declared in a __published section must be __fastcall. This also applies to hoisted properties. E2122: Function call terminated by unhandled exception 'value' at address 'addr' This message is emitted when an expression you are evaluating while debugging includes http://docs.embarcadero.com/products/rad_studio/radstudio2007/RS2007_helpupdates/HUpdate4/EN/html/devwin32/cppcompmessagespart_xml.html a function call that terminates with an unhandled exception. For example, if in the debugger's evaluate dialog, you request an evaluation of the expression foo()+1 and the execution of the function foo() causes a GP fault, this evaluation produces the above error message.You may also see this message in the watches window because it also displays the results of evaluating an expression. E2506: Explicit specialization of 'specifier' is ambiguous: must specify template arguments In the following code, explicit template arguments are necessary: E2483: Array dimension 'specifier' could not be determined If, during instantiation of a type, an array dimension cannot be computed—usually this is due to some other error which would be reported—then this error will result. For example, if an array dimension is dependent upon a template parameter but an error occurs while it is being parsed and the template argument being substituted does not yield a legal constant expression, this error is displayed. E2509: Value out of range The inline assembler has detected a numeric overflow in one of your expressions. Make sure all of your numbers can fit in 32 bits. E2510: Operand size mismatch Help is not available for this item. E2050: __declspec(delphireturn) class 'class' must have exactly one data member This is an internal compiler error. A class mar

Most of the C or even Unix function calls return -1 or NULL in case of any error and set an error code errno. It is set as a global variable and indicates an error occurred during any function list of error call. You can find various error codes defined in
