err/warn family of functions cheat sheet:
|
|
|
|
Print:
|
|
last component of program name
|
|
[ if fmt is non-NULL
|
|
": "
|
|
the formatted error message
|
|
]
|
|
[ if function name does not end in x
|
|
": "
|
|
strerror(errno)
|
|
]
|
|
newline
|
|
|
|
Then if function name has "err" in it, quit with exit code `eval'.
|
|
|
|
BSD's -x versions actually print ": " at the end if passed NULL, so I
|
|
duplicate that behavior. Passing these functions NULL is kind of useless
|
|
though.
