377 *
378 * Arguments : pgrp is a pointer to the event flag group.
379 *
380 * pname is a pointer to an ASCII string that will receive the name of the event flag
381 * group. The string must be able to hold at least OS_FLAG_NAME_SIZE characters.
382 *
383 * perr is a pointer to an error code that can contain one of the following values:
384 *
385 * OS_ERR_NONE if the requested task is resumed
386 * OS_ERR_EVENT_TYPE if 'pevent' is not pointing to an event flag group
387 * OS_ERR_PNAME_NULL You passed a NULL pointer for 'pname'
388 * OS_ERR_FLAG_INVALID_PGRP if you passed a NULL pointer for 'pgrp'
389 * OS_ERR_NAME_GET_ISR if you called this function from an ISR
390 *
391 * Returns : The length of the string or 0 if the 'pgrp' is a NULL pointer.
