This document is not 39intended as an overview or a tutorial for the C library. Each library 40function is listed with a synopsis of its use, a brief description, 41return values (including error handling), and portability issues. 42 43 <p>Some of the library functions depend on support from the underlying 44operating system and may not be available on every platform. For 45embedded systems in particular, many of these underlying operating 46system services may not be available or may not be fully functional. 47The specific operating system subroutines required for a particular 48library function are listed in the “Portability” section of the 49function description. See <a href="Syscalls.html#Syscalls">Syscalls</a>, for a description of the 50relevant operating system calls. 51 52 </body></html> 53 54
