Function Documentation

create_timestamp()

WS_DLL_PUBLIC uint64_t create_timestamp

(

void

)

Fetch the number of microseconds since midnight (0 hour), January 1, 1970.

get_resource_usage()

WS_DLL_PUBLIC void get_resource_usage	(	double *	user_time,
		double *	sys_time
	)

Fetch the process CPU time.

Fetch the current process user and system CPU times, convert them to seconds, and store them in the provided parameters.

Parameters

user_time	Seconds spent in user mode.
sys_time	Seconds spent in system (kernel) mode.

log_resource_usage()

WS_DLL_PUBLIC void log_resource_usage	(	bool	reset_delta,
		const char *	format,
			...
	)

Print the process CPU time followed by a log message.

Print the current process user and system CPU times along with the times elapsed since the times were last reset.

Parameters

reset_delta	Reset the delta times. This will typically be true when logging the first measurement and false thereafter.
format	Printf-style format string. Passed to g_string_vprintf.
...	Parameters for the format string.

mktime_utc()

WS_DLL_PUBLIC time_t mktime_utc

(

struct tm *

tm

)

Converts a broken down date representation, relative to UTC, to a timestamp

tm_is_valid()

WS_DLL_PUBLIC bool tm_is_valid

(

struct tm *

tm

)

Validate the values in a time_t. Currently checks tm_year, tm_mon, tm_mday, tm_hour, tm_min, and tm_sec; disregards tm_wday, tm_yday, and tm_isdst.

Parameters

tm	The struct tm to validate.
