/** |
|
* @file err.h |
|
* |
|
* Simple error/warning functions, heavily inspired by the BSD functions of |
|
* the same names. |
|
* |
|
* The err() and warn() family of functions display a formatted error |
|
* message on the standard error output. In all cases, the last |
|
* component of the program name, a colon character, and a space are |
|
* output. If the fmt argument is not NULL, the printf(3)-like formatted |
|
* error message is output. The output is terminated by a newline |
|
* character. |
|
* |
|
* The err(), errc(), verr(), verrc(), warn(), warnc(), vwarn(), and |
|
* vwarnc() functions append an error message obtained from strerror(3) |
|
* based on a supplied error code value or the global variable errno, |
|
* preceded by another colon and space unless the fmt argument is NULL. |
|
* |
|
* In the case of the errc(), verrc(), warnc(), and vwarnc() functions, |
|
* the code argument is used to look up the error message. |
|
* |
|
* The err(), verr(), warn(), and vwarn() functions use the global |
|
* variable errno to look up the error message. |
|
* |
|
* The errx() and warnx() functions do not append an error message. |
|
* |
|
* The err(), verr(), errc(), verrc(), errx(), and verrx() functions do |
|
* not return, but exit with the value of the argument eval. |
