10.2.1. Process Termination -
anyos_find_process
The
different versions of this function use either the Gamma
function qnx_name_locate
or the Gamma function access to
check if either the qserve or
nserve commands, identified by the
name or
command parameter, are
running.
10.2.1.1. For Linux (lib/linux.g)
/*--------------------------------------------------------------------
* Function: anyos_find_process
* Returns: t or nil
* Description: A wrapper for the qnx_name_locate() function used in
* anyos_start_qnserves(). Allows for alternate code in
* QNX 6.
*------------------------------------------------------------------*/
function anyos_find_process(command, name)
{
qnx_name_locate (0, name, 0);
}
10.2.1.2. For QNX 4 (lib/qnx4.g)
/*--------------------------------------------------------------------
* Function: anyos_find_process
* Application: common
* Returns: t or nil
* Description: A wrapper for the qnx_name_locate() function used in
* anyos_start_qnserves(). Allows for alternate code in
* QNX 6.
*------------------------------------------------------------------*/
function anyos_find_process(command, name)
{
qnx_name_locate (0, name, 0);
}
10.2.1.3. For QNX 6 (lib/qnx6.g)
/*--------------------------------------------------------------------
* Function: anyos_find_process
* Application: common
* Returns: t or nil
* Description: Finds a process based on the name of a command, rather
* than the name of a processes (as is done in QNX 4 and
* Linux). The qnx_name_locate function is not available
* in QNX 6 due to its unique kernel architecture.
*------------------------------------------------------------------*/
function anyos_find_process(command, name)
{
if(access(string("/dev/", command), 0) == -1)
nil;
else
t;
}
10.2.2. Reassigning Strings -
anyos_assign
The QNX
versions of this function use the Gamma switch
statement to select and reassign strings based on
OS-specific needs. The function allows for generic PhabReadWidgetFile
calls to Photon 1.14 widget files for QNX 4, or Photon 2
widget files for QNX 6, as well as a few other strings not
held in common.
10.2.2.1. For Linux (lib/linux.g)
/*--------------------------------------------------------------------
* Function: anyos_assign
* Returns: function
* Description: Not currently used in Linux. Used in QNX 4 and QNX 6
* for making OS-dependent assignments.
*------------------------------------------------------------------*/
function anyos_assign(str)
{
nil;
}
10.2.2.2. For QNX 4 (lib/qnx4.g)
/*--------------------------------------------------------------------
* Function: anyos_assign
* Application: common
* Returns: a string
* Description: Creates a way to reassign a single string to different
* strings, based on the OS.
*------------------------------------------------------------------*/
function anyos_assign(str)
{
switch(str)
{
case "control_widgetfile": "phcontrolwindow/wgt/Ptcontrol.wgtw";
case "monitor_widgetfile": "phmonitorwin/wgt/Ptmonitor.wgtw";

10.2.2.3. For QNX 6 (lib/qnx6.g)

* Returns: a string
* Description: Creates a way to reassign a single string to different
