5.9.2. RTEMS API

This API represents the driver interface of the module from an RTEMS user application's
perspective.

The driver functionality is accessed through the RTEMS POSIX API for ease of use. In case
of a failure on a function call, the

errno

value is set for determining the cause.

5.9.2.1. Function int open(...)

Opens access to the specified GPIO pin, but do not reset the pin interface and instead
retains the settings from any previous access.

Argument name

Type

Direction

Description

pathname

const char *

in

The absolute path to the GPIO pin to be
opened. All possible paths are given by
"/dev/gpioX" where X matches 0-31. The actual
number of devices available depends on the
current hardware configuration.

flags

int

in

Access mode flag, O_RDONLY, O_WRONLY
or O_RDWR.

Return value

Description

Fildes

A file descriptor for the device on
success

-1

See

errno

values

errno values

EALREADY

Device is already open

EINVAL

Invalid options

5.9.2.2. Function int close(...)

Closes access to the GPIO pin.

Argument name

Type

Direction

Description

fd

int

in

File descriptor received at open.

Return value

Description

0

Device closed successfully

-1

See

errno

values

errno values

EINVAL

Invalid options

5.9.2.3. Function ssize_t read(...)

Reads the current value of the specified GPIO pin. If no edge detection have been enabled,
this call will return immediately. With edge detection enabled, this call will block with a
timeout until the pin changes status such that it triggers the edge detection. The timeout can
be adjusted using an ioctl command, but defaults to zero - blocking indefinitely, see also
5.9.2.5.
