NAME

       stdio.h, stdio - standard buffered input/output

SYNOPSIS

       #include <stdio.h>

DESCRIPTION

       The <stdio.h> header defines the following macros as positive integer constant expressions:

       BUFSIZ	    size of <stdio.h> buffers

       _IOFBF	    input/output fully buffered

       _IOLBF	    input/output line buffered

       _IONBF	    input/output unbuffered

       L_ctermid    maximum size of character array to hold ctermid() output

       L_tmpnam     maximum size of character array to hold tmpnam() output

       SEEK_CUR     seek relative to current position

       SEEK_END     seek relative to end-of-file

       SEEK_SET     seek relative to start-of-file

       The following macros are defined as positive integer constant expressions that denote implementation limits:

       {FILENAME_MAX}	 Maximum size in bytes of the longest filename string that the implementation guarantees can be opened.

       {FOPEN_MAX}	 Number of streams that the implementation guarantees can be open simultaneously. The value is at least eight.

       {TMP_MAX}	 Minimum  number of unique filenames generated by tmpnam(). Maximum number of times an application can call tmpnam() reli-
			 ably. The value of {TMP_MAX} is at least 25. On XSI-conformant systems, the value of {TMP_MAX} is at least 10000.

       The following macro name is defined as a negative integer constant expression:

       EOF    end-of-file return value

       The following macro name is defined as a null pointer constant:

       NULL    null pointer

       The following macro name is defined as a string constant:

       P_tmpdir    default directory prefix for tempnam()

       The following is defined as expressions of type "pointer to FILE" point to the FILE objects associated,	respectively,  with  the  standard
       error, input, and output streams:

       stderr	 standard error output stream

       stdin	 standard input stream

       stdout	 standard output stream

       The following data types are defined through typedef:

       FILE	  structure containing information about a file

       fpos_t	  non-array type containing all information needed to specify uniquely every position within a file

       va_list	  as described in <stdarg.h>

       size_t	  as described in <stddef.h>
