## Enumeration Type Documentation

enum rpm_machtable_e

Build and install arch/os table identifiers.

Todo:
  Eliminate from API.

Enumerator:

  RPM_MACHTABLE_INSTARCH | Install platform architecture.
  RPM_MACHTABLE_INSTOS | Install platform operating system.
  RPM_MACHTABLE_BUILDARCH | Build platform architecture.
  RPM_MACHTABLE_BUILDOS | Build platform operating system.

## Function Documentation

void rpmFreeRpmrc | ( | void |  | ) |

Destroy rpmrc arch/os compatibility tables.

Todo:
  Eliminate from API.

void rpmGetArchInfo | ( | const char ** | name,
|  | int * | num |
| ) |  |  |

Return current arch name and/or number.

Todo:
  Generalize to extract arch component from target_platform macro.

Return values:

  | name | address of arch name (or NULL)
  | num | address of arch number (or NULL)

void rpmGetMachine | ( | const char ** | arch,
|  | const char ** | os |
| ) |  |  |

Return current arch/os names.

Deprecated:
  Use rpmExpand on _target_* macros.

Todo:
  Eliminate from API.

Return values:

  | arch | address of arch name (or NULL)
  | os | address of os name (or NULL)

void rpmGetOsInfo | ( | const char ** | name,
|  | int * | num |
| ) |  |  |

Return current os name and/or number.

Todo:
  Generalize to extract os component from target_platform macro.

Return values:

  | name | address of os name (or NULL)
  | num | address of os number (or NULL)

const char* rpmGetVar | ( | int | var | ) |

Return value of an rpmrc variable.

Deprecated:
  Use rpmExpand() with appropriate macro expression.

Todo:
  Eliminate from API.

Definition at line 1209 of file rpmrc.c.

References rpmGetVarArch().

Referenced by doReadRC(), rpmReadRC(), rpmShowRC(), setPathDefault(), setVarDefault(), and unsatisfiedDepend().

int rpmMachineScore | ( | int | type,
|  | const char * | name |
| ) |  |  |

Return arch/os score of a name.

An arch/os score measures the "nearness" of a name to the currently running (or defined) platform arch/os. For example, the score of arch "i586" on an i686 platform is (usually) 2. The arch/os score is used to select one of several otherwise identical packages using the arch/os tags from the header as hints of the intended platform for the package.

Todo:
  Rewrite to use RE's against config.guess target platform output.

Parameters:

  | type | any of the RPM_MACHTABLE_* constants
  | name | name

Returns:
  arch score (0 is no match, lower is preferred)

Parameters:

## Variable Documentation

const char* macrofiles

List of macro files to read when configuring rpm.

This is a colon separated list of files. URI's are permitted as well, identified by the token '://', so file paths must not begin with '//'.
