Writes an error to the Traffic Server error log.
void INKError (const char
*
fmt
, ...)
is the fmt
printf
format description.
...
is the argument for the format
description.
It is sometimes useful to log messages when errors occur.
Traffic Server has a global error log file to which it writes
such messages, and the function INKError
is the API interface to
this error log. INKError
is similar to
printf
except that instead of writing the output to the C
standard output, INKError
writes output to
the Traffic Server error log. One advantage of
INKError
over printf
is that each call is
atomically placed into the error log and is not garbled with
other error entries (this is not an issue in single-threaded
programs, but is a definite nuisance in multi-threaded
programs).
