Function Documentation

std::string hpp::debug::getFilename	(	const std::string &	filename,
		const std::string &	packageName
	)

Compute the path of a file in the logging prefix.

Apply the same rules than getPrefix and append the filename to build the whole path.

Parameters

filename	Name of the file (will be appended to the prefix)
packageName	name of the package, must be a valid Unix filename (the use of PACKAGE_TARNAME is strongly encouraged).

std::string hpp::debug::getPrefix

(

const std::string &

packageName

)

Compute the logging prefix.

This method returns the logging prefix. It means the directory where all debugging output must be stored.

The prefix is $localstatedir/log/$packagename.

• localstatedir: [prefix]/var (by default /usr/local/var)
• packagename: this function's first argument

To use this function, first include config.h and use the PACKAGE_TARNAME provided by Autoheader as this function's first argument.

The prefix $localstatedir/log can be overrided by the environment variable HPP_LOGGINGDIR.

Parameters

packageName

name of the package, must be a valid Unix filename (the use of PACKAGE_TARNAME is strongly encouraged).
