NAME

       nbdkit_parse_delay - parse human-readable delays and sleeps for nbdkit

SYNOPSIS

        #include <nbdkit-plugin.h>

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

DESCRIPTION

       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).

RETURN VALUE

       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-python-plugin(3):

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