xo_warn(3) [freebsd man page]

LIBXO(3)						   BSD Library Functions Manual 						  LIBXO(3)

NAME
xo_err -- emit errors and warnings in multiple formats LIBRARY
library ``libxo'' SYNOPSIS
#include <libxo/xo.h> void xo_warn(const char *fmt, ...); void xo_warnx(const char *fmt, ...); void xo_warn_c(int code, const char *fmt, ...); void xo_warn_hc(xo_handle_t *xop, int code, const char *fmt, ...); void xo_err(int eval, const char *fmt, ...); void xo_errc(int eval, int code, const char *fmt, ...); void xo_errx(int eval, const char *fmt, ...); void xo_message(const char *fmt, ...); void xo_message_c(int code, const char *fmt, ...); void xo_message_hc(xo_handle_t *xop, int code, const char *fmt, ...); void xo_message_hcv(xo_handle_t *xop, int code, const char *fmt, va_list vap); DESCRIPTION
Many programs make use of the standard library functions err(3) and warn(3) to generate errors and warnings for the user. libxo wants to pass that information via the current output style, and provides compatible functions to allow this. These functions display the program name, a colon, a formatted message based on the arguments, and then optionally a colon and an error mes- sage associated with either errno or the code parameter. EXAMPLE: if (open(filename, O_RDONLY) < 0) xo_err(1, "cannot open file '%s'", filename); ADDITIONAL DOCUMENTATION
