Prima::Utils(3)

NAME
Prima::Utils - miscellanneous routines

DESCRIPTION
The module contains several routines, implemented in C. These routines can be accessed via "Prima::Utils::" prefix.

API

beep [ FLAGS = mb::Error ]
    Invokes the system-depended sound and/or visual bell, corresponding to one of following constants:

      mb::Error
      mb::Warning
      mb::Information
      mb::Question

get_gui
    Returns one of "gui::XXX" constants, reflecting the graphic user interface used in the system:

       gui::Default
       gui::PM
       gui::Windows
       gui::XLib
       gui::OpenLook
       gui::Motif
    The meaning of the return value is somewhat vague, and might be deprecated in future releases.

get_os
    Returns one of "apc::XXX" constants, reflecting the platfrom. Currently, the list of the supported platforms is:

       apc::Os2
       apc::Win32
       apc::Unix

ceil DOUBLE
    Obsolete function.

    Returns stdlib's ceil() of DOUBLE

floor DOUBLE
    Obsolete function.

    Returns stdlib's floor() of DOUBLE

getdir PATH
    Reads content of PATH directory and returns array of string pairs, where the first item is a file name, and the second is a file type.

    The file type is a string, one of the following:

      "fifo" - named pipe
      "chr"  - character special file
      "dir"  - directory
      "blk"  - block special file
      "reg"  - regular file
      "lnk"  - symbolic link
      "sock" - socket
      "wht"  - whiteout
    This function was implemented for faster directory reading, to avoid successive call of "stat" for every file.

query_drives_map [ FIRST_DRIVE = ""A:"" ]
    Returns anonymous array to drive letters, used by the system. FIRST_DRIVE can be set to other value to start enumeration from. Some OSes can probe eventual diskette drives inside the drive enumeration routines, so there is a chance to increase responsiveness of the function it might be reasonable to set FIRST_DRIVE to "C:" string.

    If the system supports no drive letters, empty array reference is returned ( unix ).

query_drive_type DRIVE
    Returns one of "dt::XXX" constants, describing the type of drive, where DRIVE is a 1-character string. If there is no such drive, or the system supports no drive letters ( unix ), "dt::None" is returned.

       dt::None
       dt::Unknown
       dt::Floppy
       dt::HDD
       dt::Network
       dt::CDROM
       dt::Memory

sound [ FREQUENCY = 2000, DURATION = 100 ]
    Issues a tone of FREQUENCY in Hz with DURATION in milliseconds.

username
    Returns the login name of the user. Sometimes is preferred to the perl-provided "getlogin" ( see the getlogin entry in the perlfunc manpage ) .

xcolor COLOR
    Accepts COLOR string on one of the three formats:

      #rgb
      #rrggbb
      #rrrgggbbb
    and returns 24-bit RGB integer value.
