NAME

zttest --- Test if the zaptel timer provides timely response  

SYNOPSIS

zttest [ -v ]

 

DESCRIPTION

zttest zttest runs a timing test in a loop and prints the result of each loop. The test is as follows:

It reads 8192 bytes from the zaptel timer device (/dev/zap/pseudo). This should take exactly 8000 ms . It uses calls to gettimeofday(2) before and after that read to check that indeed exactly 8000ms have passed.

Values of 100% and 99.99% Are normally considered a definite pass. Values of 99.98% and 99.97% are probably OK as well.

 

OPTIONS

-v
Be more verbose: print one line per test.

-c count

Run for count times instead of running forever.

 

FILES

/dev/zap/pseudo
The device file used to access the zaptel timer.
