Detailed Description

Frontend base for schroot programs.

This class is used to "run" schroot programs. It contains functionality common to all programs, such as help and version output.

Definition at line 35 of file schroot-base-main.h.


Constructor & Destructor Documentation

main::main ( std::string const &  program_name,
std::string const &  program_usage,
options::ptr const &  program_options 
)

The constructor.

Parameters:
program_name the program name.
program_usage the program usage message.
program_options the command-line options to use.

Definition at line 41 of file schroot-base-main.cc.

main::~main (  )  [virtual]

The destructor.

Reimplemented in schroot_listmounts::main, schroot::main, schroot_releaselock::main, dchroot::main, and dchroot_dsa::main.

Definition at line 50 of file schroot-base-main.cc.


Member Function Documentation

int main::run ( int  argc,
char *  argv[] 
)

Run the program.

Parameters:
argc the number of arguments
argv argument vector
Returns:
0 on success, 1 on failure or the exit status of the chroot command.

virtual int schroot_base::main::run_impl (  )  [protected, pure virtual]

Run the program.

This is the program-specific run method which must be implemented in a derived class.

Returns:
0 on success, 1 on failure or the exit status of the chroot command.

Implemented in schroot_listmounts::main, schroot::main_base, and schroot_releaselock::main.
