Detailed Description

Reading config files and getting some important configuration values.

Enumeration Type Documentation

◆ 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 46 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
archname 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.
Return values
nameaddress of arch name (or NULL)
numaddress 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.
Return values
nameaddress of os name (or NULL)
numaddress 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
typeany of the RPM_MACHTABLE_* constants
namename
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
filecolon separated files to read (NULL uses default)
targettarget platform (NULL uses default)
Returns
0 on success, -1 on error

◆ rpmShowRC()

int rpmShowRC ( FILE *  fp)

Display current rpmrc (and macro) configuration.

Parameters
fpoutput file handle
Returns
0 always

Variable Documentation

◆ macrofiles

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 '//'.
