INTRO(3S)               COMMAND REFERENCE               INTRO(3S)



NAME
     intro - standard buffered input/output package

DESCRIPTION
     The functions described in section 3S constitute a user-
     level buffering scheme.  The in-line macros getc and
     putc(3s) handle characters quickly.  The higher level
     routines gets, fgets, scanf, fscanf, fread, puts, fputs,
     printf, fprintf, and fwrite all use getc and putc; they can
     be freely intermixed.

     These functions constitute the standard I/O package; see
     stdio(3s) . These functions are in the C library.
     Declarations for these functions may be obtained from the
     include file <stdio.h> .

CAVEATS
     The standard buffered functions do not interact well with
     certain other library and system functions, especially vfork
     and abort.
