NAME

       comedi_command_test - test streaming input/output configuration

SYNOPSIS

       #include <comedilib.h>

       int comedi_command_test (comedi_t * device, comedi_cmd * command);

DESCRIPTION

       The function comedi_command_test() tests the command structure pointed to by the parameter
       command and returns an integer describing the testing stages that were sucessfully passed.
       In  addition,  if  elements  of  the  command structure are invalid, they may be modified.
       Source elements are modified to remove invalid source  triggers.   Argument  elements  are
       adjusted or rounded to the nearest valid value.

       The meanings of the return value are as follows.

       0 indicates a valid command.

       1 indicates that one of the *_src members of the command contained an unsupported trigger.
       The bits corresponding to the unsupported triggers are zeroed.

       2 indicates that the particular combination of *_src settings  is  not  supported  by  the
       driver,  or  that  one  of the *_src members has the bit corresponding to multiple trigger
       sources set at the same time.

       3 indicates that one of the *_arg members of the command  is  set  outside  the  range  of
       allowable  values.   For  instance,  an argument for a TRIG_TIMER source which exceeds the
       board's maximum speed.  The invalid *_arg members will be adjusted to valid values.

       4 indicates that one of the *_arg members required adjustment.  For instance, the argument
       of a TRIG_TIMER source may have been rounded to the nearest timing period supported by the
       board.

       5 indicates that some aspect of the command's chanlist is unsupported by the  board.   For
       example, some board's require that all channels in the chanlist use the same range.
