(command-line-arguments) => vector
Returns a vector of strings: the arguments supplied to the program by the user or the operating system.
(dump-heap filename procedure) => unspecified
Dump a heap image to the named file that will start up with the supplied procedure. Before procedure is called, command line arguments will be parsed and any init procedures registered with add-init-procedure! will be called.
Note: Currently, heap dumping is only available with the stop-and-copy collector (-stopcopy command line option), although the heap image can be used with all the other collectors.
(dump-interactive-heap filename) => unspecified
Dump a heap image to the named file that will start up with the standard read-eval-print loop. Before the read-eval-print loop is called, command line arguments will be parsed and any init procedures registered with add-init-procedure! will be called.
Note: Currently, heap dumping is only available with the stop-and-copy collector (-stopcopy command line option), although the heap image can be used with all the other collectors.
(getenv key) => string | #f
Returns the operating system environment mapping for the string key, or #f if there is no mapping for key.
(system command) => status
Send the command to the operating system's command processor and return the command's exit status, if any. On Unix, command is a string and status is an exact integer.
