This document is not -intended as an overview or a tutorial for the C library. Each library -function is listed with a synopsis of its use, a brief description, -return values (including error handling), and portability issues. - -Some of the library functions depend on support from the underlying -operating system and may not be available on every platform. For -embedded systems in particular, many of these underlying operating -system services may not be available or may not be fully functional. -The specific operating system subroutines required for a particular -library function are listed in the ``Portability'' section of the -function description. @xref{Syscalls}, for a description of the -relevant operating system calls. - -@include targetdep.tex - -@node Arglists -@chapter Variable Argument Lists - -The @code{printf} family of functions is defined to accept a variable -number of arguments, rather than a fixed argument list. You can define -your own functions with a variable argument list, by using macro -definitions from either @file{stdarg.h} (for compatibility with ANSI C) -or from @file{varargs.h} (for compatibility with a popular convention -prior to ANSI C). - -@menu -* Stdarg:: -* Varargs:: -@end menu - -@node Stdarg -@section ANSI-standard macros, @file{stdarg.h} - -In ANSI C, a function has a variable number of arguments when its -parameter list ends in an ellipsis (@code{...}). The parameter list -must also include at least one explicitly named argument; that argument -is used to initialize the variable list data structure. - -ANSI C defines three macros (@code{va_start}, @code{va_arg}, and -@code{va_end}) to operate on variable argument lists. @file{stdarg.h} -also defines a special type to represent variable argument lists: this -type is called @code{va_list}. - -@menu -* va_start:: -* va_arg:: -* va_end:: -@end menu - -@page -@node va_start -@subsection Initialize variable argument list -@findex va_start -@strong{Synopsis} -@example -#include <stdarg.h> -void va_start(va_list @var{ap}, @var{rightmost}); -@end example - -@strong{Description}@* -Use @code{va_start} to initialize the variable argument list @var{ap}, -so that @code{va_arg} can extract values from it. @var{rightmost} is -the name of the last explicit argument in the parameter list (the -argument immediately preceding the ellipsis @samp{...} that flags -variable arguments in an ANSI C function header). You can only use -@code{va_start} in a function declared using this ellipsis notation -(not, for example, in one of its subfunctions). - -@strong{Returns}@* -@code{va_start} does not return a result. - -@strong{Portability}@* -ANSI C requires @code{va_start}. - -@page -@node va_arg -@subsection Extract a value from argument list -@findex va_arg -@strong{Synopsis} -@example -#include <stdarg.h> -@var{type} va_arg(va_list @var{ap}, @var{type}); -@end example - -@strong{Description}@* -@code{va_arg} returns the next unprocessed value from a variable -argument list @var{ap} (which you must previously create with -@var{va_start}). Specify the type for the value as the second parameter -to the macro, @var{type}. - -You may pass a @code{va_list} object @var{ap} to a subfunction, and use -@code{va_arg} from the subfunction rather than from the function -actually declared with an ellipsis in the header; however, in that case -you may @emph{only} use @code{va_arg} from the subfunction. ANSI C does -not permit extracting successive values from a single variable-argument -list from different levels of the calling stack. - -There is no mechanism for testing whether there is actually a next -argument available; you might instead pass an argument count (or some -other data that implies an argument count) as one of the fixed arguments -in your function call. - -@strong{Returns}@* -@code{va_arg} returns the next argument, an object of type @var{type}. - -@strong{Portability}@* -ANSI C requires @code{va_arg}. - -@page -@node va_end -@subsection Abandon a variable argument list -@findex va_end -@strong{Synopsis} -@example -#include <stdarg.h> -void va_end(va_list @var{ap}); -@end example - -@strong{Description}@* -Use @code{va_end} to declare that your program will not use the variable -argument list @var{ap} any further. - -@strong{Returns}@* -@code{va_end} does not return a result. - -@strong{Portability}@* -ANSI C requires @code{va_end}. - -@node Varargs -@section Traditional macros, @file{varargs.h} - -If your C compiler predates ANSI C, you may still be able to use -variable argument lists using the macros from the @file{varargs.h} -header file. These macros resemble their ANSI counterparts, but have -important differences in usage. In particular, since traditional C has -no declaration mechanism for variable argument lists, two additional -macros are provided simply for the purpose of defining functions with -variable argument lists. - -As with @file{stdarg.h}, the type @code{va_list} is used to hold a data -structure representing a variable argument list. - -@menu -* va_alist:: -* va_start-trad:: -* va_arg-trad:: -* va_end-trad:: -@end menu - -@page -@node va_alist -@subsection Declare variable arguments -@findex va_alist -@findex va_dcl -@strong{Synopsis} -@example -#include <varargs.h> -@var{function}(va_alist) -va_dcl -@end example - -@strong{Description}@* -To use the @file{varargs.h} version of variable argument lists, you must -declare your function with a call to the macro @code{va_alist} as its -argument list, and use @code{va_dcl} as the declaration. @emph{Do not -use a semicolon after @code{va_dcl}.} - -@strong{Returns}@* -These macros cannot be used in a context where a return is syntactically -possible. - -@strong{Portability}@* -@var{va_alist} and @var{va_dcl} were the most widespread method of -declaring variable argument lists prior to ANSI C. - -@page -@node va_start-trad -@subsection Initialize variable argument list -@findex va_start -@strong{Synopsis} -@example -#include <varargs.h> -va_list @var{ap}; -va_start(@var{ap}); -@end example - -@strong{Description}@* -With the @file{varargs.h} macros, use @code{va_start} to initialize a -data structure @var{ap} to permit manipulating a variable argument list. -@var{ap} must have the type @var{va_alist}. - -@strong{Returns}@* -@code{va_start} does not return a result. - -@strong{Portability}@* -@code{va_start} is also defined as a macro in ANSI C, but the -definitions are incompatible; the ANSI version has another parameter -besides @var{ap}. - -@page -@node va_arg-trad -@subsection Extract a value from argument list -@findex va_arg -@strong{Synopsis} -@example -#include <varargs.h> -@var{type} va_arg(va_list @var{ap}, @var{type}); -@end example - -@strong{Description}@* -@code{va_arg} returns the next unprocessed value from a variable -argument list @var{ap} (which you must previously create with -@var{va_start}).
