nbdkit_parse_delay - Man Page

 #include <nbdkit-plugin.h>

 int nbdkit_parse_delay (const char *what, const char *str,
                         unsigned *sec, unsigned *nsec);

The utility function nbdkit_parse_delay can be used to parse configuration parameters on the nbdkit(1) command line specifying delays and sleeps.

The str parameter is a string in one of the following formats:

1

1.2

1.2s

Seconds

1.2ms

120ms

Milliseconds

1.2us

1.2μs

120μs

Microseconds

1ns

Nanoseconds, the smallest possible time division for this function.

The what parameter is printed in error messages to provide context.

The output (sec, nsec) can be passed straight to nbdkit_nanosleep(3).

On success the function returns 0 and sets *sec and *nsec to the seconds and nanoseconds parsed.

If there is an error it calls nbdkit_error(3) and returns -1. In this case, *sec and *nsec are not touched.

In nbdkit-ocaml-plugin(3):

 NBDKit.parse_delay : string -> string -> int * int

In nbdkit-python-plugin(3):

 import nbdkit
 (sec, nsec) = nbdkit.parse_delay(what, str)

nbdkit_parse_delay was added in nbdkit 1.40.
