FGETU8(3)             DragonFly Library Functions Manual             FGETU8(3)

NAME
     fgetu8 - utf-8 library function manual page

SYNOPSIS
     #include <utf-8.h>

     unsigned int
     fgetu8(FILE *input);

     unsigned int
     utf8fgetc(FILE *input);

     unsigned int
     utf8getc(FILE *input);

     unsigned int
     utf8getchar();

DESCRIPTION
     The fgetu8() function of utf-8 library reads one or more bytes from a
     UTF-8 formatted text file, and converts them to single UTC-4 (Unicode)
     value.

     utf8fgetc() and utfgetc() are macros which simply give fgetu8() a name
     that may be more convenient to remember. They are defined in <utf-8.h>.

     The fgetu8() function and the macros take one argument: input, which can
     be any open file.

     The utf8getchar() macro reads input from stdin.

RETURN VALUES
     If input is NULL, or if a premature end-of-file condition occurs,
     fgetu8() returns EOF.  If input contains valid UTF-8 codes, fgetu8()
     returns the converted UTC-4 value. Otherwise, it returns UTF8INVALID,
     defined in <utf-8.h>.
