35 | # modified version of cerror |
| 36 | # | |
| 37 | # The idea is that every time an error occurs in a system call | |
| 38 | # I want a special function "syserr" called. This function will | |
| 39 | # either print a message and exit or do nothing depending on | |
| 40 | # defaults and use of "onsyserr". | |
