pmd_attr_init()

Initialize pmd_attr_t structure with default values

Synopsis:

#include <sys/pm.h>

void pmd_attr_init(pmd_attr_t *pmd);

Arguments:

pmd

Pointer to the pmd_attr_t structure.

Library:

libpm

Description:

The pmd_attr_init() function initializes a pmd_attr_t with default values:

• pmd->hdl to set an invalid handle
• pmd->cur_attr and pmd->new_attr are set to NULL
• pmd->setpower is set to a default function that returns an EINVAL error.

All other fields in pmd are set to 0.

After calling pmd_attr_init(), a driver should call the following to fully initialize the structure:

• Call pmd_attr_setmodes() to specify the device's supported power modes
• Call pmd_attr_setpower() to specify the driver's setpower() function.

Returns:

For more information, see the device driver chapter.
