NAME
SYNOPSIS
DESCRIPTION
sp( ) – spawn a task with default parameters
int sp
(
FUNCPTR func, /* function to call */
int arg1, /* first of nine args to pass to spawned task */
int arg2,
int arg3,
int arg4,
int arg5,
int arg6,
int arg7,
int arg8,
int arg9
)
This command spawns a specified function as a task with the following defaults:
priority:
100
stack size:
20,000 bytes
task ID:
highest not currently used
task options:
VX_FP_TASK - execute with floating-point coprocessor support.
task name:
A name of the form sXuN where X is the shell number and N is an integer which
increments as new tasks are spawned. The shell number depends on the number of
connected shells and on the order of connection. First connected shell has a 1 shell
number, then 2 3 4 ... If shell 2 disconnects, and another one connects, its shell number
will be 2 (first free slot number). Thus task names should look like s1u1, s1u2, s5u3,
etc.
The task ID is displayed after the task is spawned.
This command can also be used to spawn a task when the agent is in external mode. The
new task is created in the context of tExcTask, and will not start running until that task
has processed the spawn request. For a task started this way, only four arguments may be
given.
