name
The name to give to the created parameter.
dir
The direction of the parameter, from the viewpoint of the component. It may be one of HAL_RO, or HAL_RW. A component may assign a value to any parameter, but other programs (such as halcmd) may only assign a value to a parameter that is HAL_RW.
data_addr
The address of the data, which must lie within memory allocated by hal_malloc.
comp_id
A HAL component identifier returned by an earlier call to hal_init.
fmt, ...
A printf-style format string and arguments.
type
The type of the parameter, as specified in hal_type_t(3hal).
The hal_param_new family of functions create a new param object.
There are functions for each of the data types that the HAL supports. Pins may only be linked to signals of the same type.
Returns a HAL status code.
