The programmer hides error messages by overriding them with exception handling. As a result of this the root error message is hidden from the user (hence 'error hiding') and so they will not be told what the actual error is. Error hiding is a bane of support engineers' jobs as it often delays the resolution of the problem by hiding information needed to identify what is going wrong.

(If you look through the system calls in Section 2, you will see that there are a few calls for which no return value is defined, but they are the exceptions.) In addition to the -1 returned to the program, the unsuccessful system call places an integer in an externally declared variable, errno. In a C program, you can determine the value in errno if your program contains the following statement: #include <errno.h> Unix Tips MondoTofu Thu, 19 Jan 2012 22:19:47 GMT
