Detailed Description

Reading config files and getting some important configuration values.

Enumeration Type Documentation

rpm_machtable_e

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.

Definition at line 45 of file rpmlib.h.

Function Documentation

rpmFreeRpmrc()

void rpmFreeRpmrc

(

void

)

Destroy rpmrc arch/os compatibility tables.

Todo:

Eliminate from API.

rpmGetArchColor()

int rpmGetArchColor

(

const char *

arch

)

Return color for an arch.

Parameters

arch	name of an architecture

Returns

color color of arch, -1 if the arch couldn't be determined

rpmGetArchInfo()

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

Return current arch name and/or number.

Todo:

Generalize to extract arch component from target_platform macro.

Parameters

[out]	name	address of arch name (or NULL)
[out]	num	address of arch number (or NULL)

rpmGetOsInfo()

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

Return current os name and/or number.

Todo:

Generalize to extract os component from target_platform macro.

Parameters

[out]	name	address of os name (or NULL)
[out]	num	address of os number (or NULL)

rpmMachineScore()

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)

rpmReadConfigFiles()

int rpmReadConfigFiles	(	const char *	file,
		const char *	target
	)

Read macro configuration file(s) for a target.

Parameters

file	colon separated files to read (NULL uses default)
target	target platform (NULL uses default)

Returns

0 on success, -1 on error

rpmShowRC()

int rpmShowRC

(

FILE *

fp

)

Display current rpmrc (and macro) configuration.

Parameters

fp	output file handle

Returns

0 always
