## Function Documentation

int check_acpi_support | ( | void |  | ) |

Checks if the system does support ACPI or not

Returns:
  SUCCESS if the system supports ACPI or, NOT_SUPPORTED

Definition at line 127 of file libacpi.c.

References NOT_SUPPORTED, and SUCCESS.

int init_acpi_acadapt | ( | global_t * | globals | ) |

Finds existing ac adapter and fills the adapt structure with the paths of the important to parse files

Parameters:

  | globals | pointer to global acpi structure
