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 successfully
       passed. In addition, if elements of the comedi_cmd 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 analog input boards require that all channels in the chanlist use
           the same input range.
