nbdkit_parse_delay(3) NBDKIT nbdkit_parse_delay(3) 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 configura- tion 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" "1.2I1/4s" "120I1/4s" 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. If "sec != NULL", set *sec to the parsed seconds. If "nsec != NULL", set *nsec to the parsed nanoseconds. If either "sec == NULL" or "nsec == NULL", the parsing is done but the cor- responding result is discarded. If there is an error it calls nbdkit_error(3) and returns -1. On error *sec and *nsec are always unchanged. LANGUAGE BINDINGS 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) HISTORY "nbdkit_parse_delay" was added in nbdkit 1.40.
