-/**
- * A wrapper for `popen()` that executes non-interactive programs and reports their exit value.
- * To redirect stdout and stderr you must do so from within the `fmt` string
- *
- * ~~~{.c}
- * int fd = 1;  // stdout
- * const char *log_file = "log.txt";
- * Process *proc_info;
- * int status;
- *
- * // Send stderr to stdout
- * shell(&proc_info, SHELL_OUTPUT, "foo 2>&1");
- * // Send stdout and stderr to /dev/null
- * shell(&proc_info, SHELL_OUTPUT,"bar &>/dev/null");
- * // Send stdout from baz to log.txt
- * shell(&proc_info, SHELL_OUTPUT, "baz %d>%s", fd, log_file);
- * // Do not record or redirect output from any streams
- * shell(&proc_info, SHELL_DEFAULT, "biff");
- * ~~~
- *
- * @param Process uninitialized `Process` struct will be populated with process data
- * @param options change behavior of the function
- * @param fmt shell command to execute (accepts `printf` style formatters)
- * @param ... variadic arguments (used by `fmt`)
