LIBXO(3) Library Functions Manual LIBXO(3) NAME xo_attr, xo_attr_h, xo_attr_hv -- Add attribute name/value pairs to formatted output LIBRARY library "libxo" SYNOPSIS #include <libxo/xo.h> int xo_attr(const char *name, const char *fmt, ...); int xo_attr_h(xo_handle_t *handle, const char *name, const char *fmt, ...); int xo_attr_hv(xo_handle_t *handle, const char *name, const char *fmt, va_list vap); DESCRIPTION The xo_attr() function emits attributes for the XML output style. The attribute value is recorded in the handle and is attached to the next field that is emitted via a xo_emit(3) call. The name parameter give the name of the attribute to be encoded. The fmt parameter gives a printf-style format string used to format the value of the attribute using any remaining arguments, or the vap para- meter as passed to xo_attr_hv(). EXAMPLE: xo_attr("seconds", "%ld", (unsigned long) login_time); struct tm *tmp = localtime(login_time); strftime(buf, sizeof(buf), "%R", tmp); xo_emit("Logged in at {:login-time}\n", buf); XML: <login-time seconds="1408336270">00:14</login-time> Since attributes are only emitted in XML, their use should be limited to meta-data and additional or redundant representations of data al- ready emitted in other form.
