int ruby_executable_node | ( | void * | n, |
int * | status | ||
) |
Checks the return value of ruby_options().
n | return value of ruby_options(). |
status | pointer to the exit status of this process. |
ruby_options() sometimes returns a special value to indicate this process should immediately exit. This function checks if the case. Also stores the exit status that the caller have to pass to exit(3) into *status
.
non-zero | if the given opaque pointer is actually a compiled source. |
0 | if the given value is such a special value. |

void ruby_sysinit | ( | int * | argc, |
char *** | argv | ||
) |
Initializes the process for ruby(1).
This function assumes this process is ruby(1) and it has just started. Usually programs that embeds CRuby interpreter should not call this function, and should do their own initialization.
