Create a software timer.

Description:: This API is used to create a software timer that has specified timing duration, timeout handling function, and trigger mode, and to return a handle by which the software timer can be referenced.

注意:

Do not use the delay interface in the callback function that handles software timer timeout.
Threre are LOSCFG_BASE_CORE_SWTMR_LIMIT timers available, change it's value when necessory.

参数:

	参数名称	描述
	uwInterval	[IN] Timing duration of the software timer to be created (unit: ms).
	ucMode	[IN] Software timer mode. Pass in one of the modes specified by enSwTmrType. There are three types of modes, one-off, periodic, and continuously periodic after one-off, of which the third mode is not supported temporarily.
	pfnHandler	[IN] Callback function that handles software timer timeout.
	pusSwTmrID	[OUT] Software timer ID created by LOS_SwtmrCreate.
	uwArg	[IN] Parameter passed in when the callback function that handles software timer timeout is called.

返回值:

	返回值	描述
	LOS_ERRNO_SWTMR_INTERVAL_NOT_SUITED	The software timer timeout interval is 0.
	LOS_ERRNO_SWTMR_MODE_INVALID	Invalid software timer mode.
	LOS_ERRNO_SWTMR_PTR_NULL	The callback function that handles software timer timeout is NULL.
	LOS_ERRNO_SWTMR_RET_PTR_NULL	The passed-in software timer ID is NULL.
	LOS_ERRNO_SWTMR_MAXSIZE	The number of software timers exceeds the configured permitted maximum number.
	LOS_OK	The software timer is successfully created.

Dependency:

los_swtmr.h: the header file that contains the API declaration.
