Function Documentation

ast_format_duration_hh_mm_ss()

void ast_format_duration_hh_mm_ss	(	int	duration,
		char *	buf,
		size_t	length
	)

Formats a duration into HH:MM:SS.

Since

12

Parameters

duration	The time (in seconds) to format
buf	A buffer to hold the formatted string'
length	The size of the buffer

   durh = duration / 3600;
   durm = (duration % 3600) / 60;
   durs = duration % 60;
   snprintf(buf, length, "%02d:%02d:%02d", durh, durm, durs);
}

ast_remaining_ms()

int ast_remaining_ms	(	struct timeval	start,
		int	max_ms
	)

Calculate remaining milliseconds given a starting timestamp and upper bound.

If the upper bound is negative then this indicates that there is no upper bound on the amount of time to wait. This will result in a negative return.

Parameters

start	When timing started being calculated
max_ms	The maximum number of milliseconds to wait from start. May be negative.

Returns

The number of milliseconds left to wait for. May be negative.

ast_time_create_by_unit_str()

struct timeval ast_time_create_by_unit_str	(	unsigned long	val,
		const char *	unit
	)

Convert the given unit value, and create a timeval object from it.

This will first attempt to convert the unit from a string to a TIME_UNIT enumeration. If that conversion fails then a zeroed out timeval object is returned.

Parameters

val	The value to convert to a timeval
unit	The time unit type of val

Returns

A timeval object

ast_time_str_to_unit()

enum TIME_UNIT ast_time_str_to_unit

(

const char *

unit

)

Convert a string to a time unit enumeration value.

This method attempts to be as flexible, and forgiving as possible when converting. In most cases the algorithm will match on the beginning of up to three strings (short, medium, long form). So that means if the given string at least starts with one of the form values it will match.

For example: us, usec, microsecond will all map to TIME_UNIT_MICROSECOND. So will uss, usecs, miscroseconds, or even microsecondvals

Matching is also not case sensitive.

Parameters

unit	The string to map to an enumeration

Returns

A time unit enumeration
