#include <sys/pm.h>

int pmd_detach(pmd_attr_t *pmd);

Arguments:

pmd

Pointer to the device's pmd_attr_t structure.

Library:

libpm

Description:

The pmd_detach() detaches the device from the power manager and invalidates the handle in pmd-> hdl.

Driver connections to the power manager are automatically detached during abnormal termination (in which case the device may be left in an unknown state that cannot be recovered from).

Returns:

0

Success.

-1

An error occurred (errno is set).

This function, currently, always succeeds.
