Define Documentation

#define PJ_TIME_VAL_ADD	(	t1,
		t2		)

Add t2 to t1 and store the result in t1. Effectively

this macro will expand as: (t1 += t2).

Parameters:

	t1	The time value to add.
	t2	The time value to be added to t1.

#define PJ_TIME_VAL_EQ	(	t1,
		t2		)

This macro will check if t1 is equal to t2.

Parameters:

	t1	The first time value to compare.
	t2	The second time value to compare.

Returns:

Non-zero if both time values are equal.

#define PJ_TIME_VAL_GT	(	t1,
		t2		)

This macro will check if t1 is greater than t2

Parameters:

	t1	The first time value to compare.
	t2	The second time value to compare.

Returns:

Non-zero if t1 is greater than t2.

#define PJ_TIME_VAL_GTE	(	t1,
		t2		)

This macro will check if t1 is greater than or equal to t2

Parameters:

	t1	The first time value to compare.
	t2	The second time value to compare.

Returns:

Non-zero if t1 is greater than or equal to t2.

#define PJ_TIME_VAL_LT	(	t1,
		t2		)

This macro will check if t1 is less than t2

Parameters:

	t1	The first time value to compare.
	t2	The second time value to compare.

Returns:

Non-zero if t1 is less than t2.

#define PJ_TIME_VAL_LTE	(	t1,
		t2		)

This macro will check if t1 is less than or equal to t2.

Parameters:

	t1	The first time value to compare.
	t2	The second time value to compare.

Returns:

Non-zero if t1 is less than or equal to t2.

#define PJ_TIME_VAL_MSEC

(

t

)

Get the total time value in miliseconds. This is the same as multiplying the second part with 1000 and then add the miliseconds part to the result.

Parameters:

t

The time value.

Returns:

Total time in miliseconds.

#define PJ_TIME_VAL_SUB	(	t1,
		t2		)

Substract t2 from t1 and store the result in t1. Effectively this macro will expand as (t1 -= t2).

Parameters:

	t1	The time value to subsctract.
	t2	The time value to be substracted from t1.
