getchar	_gettchar	Read a character from standard input.
putchar	_puttchar	Write a character to stdout.
getc	_gettc	Read a character from a stream.
fgetc	_fgettc	fgetc is equivalent to getc, but is implemented only as a function, rather than as a function and a macro.
putc	_puttc	Write a character to a stream
fputc	_fputtc	Equivalent to putc, but implemented only as a function, rather than as a function and a macro.

gets	_getts	Get a line from the stdin stream. gets then replaces the newline character with a null character ('/0') before returning the line.
fgets	_fgetts	Get a string from a stream. the fgets function retains the newline character.
puts	_putts	Write a string to stdout. replacing the string's terminating null character ('/0') with a newline character ('/n') in the output stream.
fputs	_fputfs	Write a string to a stream.
