# Predefined Constants

The constants below are defined by this extension, and will only be available when the extension has either been compiled into PHP or dynamically loaded at runtime.

The following list of constants are used to obtain information using the rpm_get_tag() function. These constants represent the tag number to be retrieved from the RPM file's header section. Descriptions are given below as to what data the tag number constants reference.

`RPMREADER_MINIMUM` (integer)
  The minimum valid value of any RPM tag number.
`RPMREADER_NAME` (integer)
  The name of the RPM package.
`RPMREADER_VERSION` (integer)
  The version of the RPM package.
`RPMREADER_RELEASE` (integer)
  The release of the RPM package.
`RPMREADER_EPOCH` (integer)
`RPMREADER_SERIAL` (integer)
`RPMREADER_SUMMARY` (integer)
  The summary text of the RPM package.
`RPMREADER_DESCRIPTION` (integer)
  The full description text of the RPM package.
`RPMREADER_BUILDTIME` (integer)
  The date and time when the RPM package was built.
`RPMREADER_BUILDHOST` (integer)
  The name of the host on which the RPM package was built.
`RPMREADER_INSTALLTIME` (integer)
`RPMREADER_SIZE` (integer)
  The size of the RPM package.
`RPMREADER_DISTRIBUTION` (integer)

`RPMREADER_OLDFILENAMES` (integer)
  The list of files in an RPM package (deprecated format). The correct way is now to use a combination of 3 tags (RPMREADER_BASENAMES, RPMREADER_DIRINDEXES, RPMREADER_DIRNAMES) in what RPM now calls "CompressedFileNames". This tag is still used in older RPM files that did not use the "CompressedFileNames" method and is maintained for backward compatibility.

`RPMREADER_BASENAMES` (integer)
  The list of the names of files in the RPM package without path information. This tag is used in conjunction with RPMREADER_DIRINDEXES and RPMREADER_DIRNAMES to reconstruct filenames in the RPM package stored with the new "CompressedFileNames" method in RPM.
`RPMREADER_DIRNAMES` (integer)
  The list of directory names used by files in the RPM package. This tag is used in conjunction with RPMREADER_BASENAMES and RPMREADER_DIRINDEXES to reconstruct filenames in the RPM package stored with the new "CompressedFileNames" method in RPM.
