Detailed Description

Utility class to access /proc/<pid>/cmdline to retrieve argc and argv


Constructor & Destructor Documentation

YCommandLine::YCommandLine ( )

Constructor. This will read /proc/<pid>/cmdline of this process.

YCommandLine::~YCommandLine ( )

Destructor.


Member Function Documentation

void YCommandLine::add ( const string &  arg)

Add a command line argument (at the end of the existing ones).

string YCommandLine::arg ( int  index) const

Return command line argument no. 'index' (from 0 on).

This might throw an YUIIndexOutOfRangeException.

int YCommandLine::argc ( ) const

Return the number of arguments in the command line. Remember that the command itself (the binary of the process) is included, so a value of 1 (not 0!) means "no additional arguments".

char ** YCommandLine::argv ( ) const

Return the arguments in a C compatible fashion: An array of pointers to characters. The data are copied with strdup(), so they are valid beyond the life time of this object (but OTOH should be released with free() at some point).

int YCommandLine::find ( const string &  argName) const

Find a command line argument 'argName' ("-display" etc.). Notice that leading minus signs must be specified in 'argName'. Since argv[0] is the program name, the search starts from argv[1].

Return the position of 'argName' (from 0 on) or -1 if not found.

string YCommandLine::operator[] ( int  index) const [inline]

Return command line argument no. 'index' (from 0 on) as operator[]:

for ( int i=0; i < cmdLine.argc(); i++ ) cout << cmdLine[i] << endl;

This might throw an YUIIndexOutOfRangeException.

void YCommandLine::remove ( int  index)

Remove command line argument no. 'index' (from 0 on).

This might throw an YUIIndexOutOfRangeException.

void YCommandLine::replace ( int  index,
const string &  arg 
)

Replace command line argument no. 'index' (from 0 on) with 'arg'.

This might throw an YUIIndexOutOfRangeException.

int YCommandLine::size ( ) const [inline]

Alias for argc() for those who like a more C++ -like syntax.
