; * CHECK THE STATUS OF FLAGS IN AN EVENT FLAG GROUP
; *
; * Description: This function is called to check the status of a combination of bits to be set or cleared
; * in an event flag group. Your application can check for ANY bit to be set/cleared or ALL
; * bits to be set/cleared.
; *
; * This call does not block if the desired flags are not present.
; *
; * Arguments : pgrp is a pointer to the desired event flag group.
; *
; * flags Is a bit pattern indicating which bit(s) (i.e. flags) you wish to check.
; * The bits you want are specified by setting the corresponding bits in
; * 'flags'. e.g. if your application wants to wait for bits 0 and 1 then
; * 'flags' would contain 0x03.
; *
; * wait_type specifies whether you want ALL bits to be set/cleared or ANY of the bits
; * to be set/cleared.
; * You can specify the following argument:
; *
; * OS_FLAG_WAIT_CLR_ALL You will check ALL bits in 'flags' to be clear (0)
; * OS_FLAG_WAIT_CLR_ANY You will check ANY bit in 'flags' to be clear (0)
; * OS_FLAG_WAIT_SET_ALL You will check ALL bits in 'flags' to be set (1)
; * OS_FLAG_WAIT_SET_ANY You will check ANY bit in 'flags' to be set (1)
; *
; * NOTE: Add OS_FLAG_CONSUME if you want the event flag to be 'consumed' by
; * the call. Example, to wait for any flag in a group AND then clear
; * the flags that are present, set 'wait_type' to:
; *
; * OS_FLAG_WAIT_SET_ANY + OS_FLAG_CONSUME
; *
; * err is a pointer to an error code and can be:
; * OS_NO_ERR No error
; * OS_ERR_EVENT_TYPE You are not pointing to an event flag group
; * OS_FLAG_ERR_WAIT_TYPE You didn't specify a proper 'wait_type' argument.
; * OS_FLAG_INVALID_PGRP You passed a NULL pointer instead of the event flag
; * group handle.
; * OS_FLAG_ERR_NOT_RDY The desired flags you are waiting for are not
; * available.
; *
; * Returns : The state of the flags in the event flag group.
; *
; * Called from: Task or ISR
