Extended Behavior of ANSI C Library Functions 

The POSIX.1 standard defines extended or additional behavior of certain
ANSI C library functions beyond those set forth in ANSI C. The enhanced
behavior does not interfere with strict ANSI C compliance.

The following ANSI C functions provide extensions or modified behavior
beyond those set forth in ANSI C when used in the POSIX/iX library
environment:

   *   setlocale()
   *   rename()
   *   abort()
   *   ANSI C time functions:
          *   ctime()
          *   gmtime()
          *   localtime()
          *   mktime()
          *   strftime()
   *   fseek()
   *   exit()
   *   fileno()
   *   fdopen()
   *   fopen()
   *   fclose()
   *   freopen()
   *   fflush()
   *   ANSI C functions that read input:
          *   fgetc()
          *   fgets()
          *   fread()
          *   getc()
          *   getchar()
          *   gets()
          *   scanf()
          *   fscanf()
   *   ANSI C functions that write output
          *   fputc()
          *   fputs()
          *   fwrite()
          *   putc()
          *   putchar()
          *   puts()
          *   printf()
          *   fprintf()
          *   vprintf()
          *   vfprintf()
   *   rewind()
   *   perror()
   *   tmpfile()
   *   ftell()
   *   remove()

Extensions required by POSIX.1 are documented in the library function
descriptions found in the HP C/iX Library Reference Manual (30026-90001).
