21 | * modified version of cerror |
| 22 | * | |
| 23 | * The idea is that every time an error occurs in a system call | |
| 24 | * I want a special function "syserr" called. This function will | |
| 25 | * either print a message and exit or do nothing depending on | |
| 26 | * defaults and use of "onsyserr". | |
