| 8 | # modified version of cerror | |
| 9 | # | |
| 10 | # The idea is that every time an error occurs in a system call | |
| 11 | # I want a special function "syserr" called. This function will | |
| 12 | # either print a message and exit or do nothing depending on | |
| 13 | # defaults and use of "onsyserr". | |
