set custom writer functions for a libxo handle

NAME

xo_set_writer – set custom writer functions for a libxo handle

LIBRARY

library “libxo”

SYNOPSIS

#include <libxo/xo.h>

void
typedef xo_ssize_t (*xo_write_func_t)(void *, const char *);

typedef void (*xo_close_func_t)(void *);

typedef int (*xo_flush_func_t)(void *);

xo_set_writer(xo_handle_t *handle, void *opaque);
"xo_write_func_t write_func"
"xo_close_func_t close_func"
"xo_flush_func_t flush_func"

DESCRIPTION

The xo_set_writer() function allows custom “write” functions which can tailor how libxo writes data. An opaque argument is recorded and passed back to the write_func function, allowing the function to acquire context information. The close_func function can release this opaque data and any other resources as needed. The flush_func function should flush any pending data associated with the opaque pointer.
