checkStack( )
NAME
checkStack( ) – print a summary of each task’s stack usage
SYNOPSIS
DESCRIPTION
void checkStack
(
int taskNameOrId /* task name or task ID; 0 = summarize all */
)
This command displays a summary of stack usage for a specified task, or for all tasks if no
argument is given. The summary includes the total stack size (SIZE), the current number
of stack bytes used (CUR), the maximum number of stack bytes used (HIGH), and the
number of bytes never used at the top of the stack (MARGIN = SIZE - HIGH). For
example:
-> checkStack t28
NAME ENTRY TID SIZE CUR HIGH MARGIN
------------ ------------ -------- ----- ----- ----- ------
t28 _foo 23e1c78 9208 832 3632 5576
The maximum stack usage is determined by scanning down from the top of the stack for
the first byte whose value is not 0xee. In VxWorks, when a task is spawned, all bytes of a
task’s stack are initialized to 0xee.
