xo_parse_args - Man Page

Text, XML, JSON, and HTML Output Emission Library (libxo, -lxo)

#include <libxo/xo.h>

int
xo_parse_args(int argc, char **argv);

int
xo_set_program(const char *name);

The xo_parse_args() function is used to process command-line arguments, which are described in xo_options(7). libxo specific options are processed and removed from the argument list so the calling application does not need to process them. If successful, a new value for argc is returned. On failure, a message it emitted and -1 is returned.

    argc = xo_parse_args(argc, argv);
    if (argc < 0)
        exit(EXIT_FAILURE);

Following the call to xo_parse_args(), the application can process the remaining arguments in a normal manner.

The xo_set_program() function sets name of the program as reported by functions like xo_failure(), xo_warn(), xo_err(), etc. The program name is initialized by xo_parse_args(), but subsequent calls to xo_set_program() can override this value.

Note that the value is not copied, so the memory passed to xo_set_program() (and xo_parse_args()) must be maintained by the caller.
