old style C function

[westfork]

Hi all

Please can someone help me about old style C function?
The following declaration:

int foo (va_alist)
va_dcl
{
/* ... */
}

is equal to with the usual C style prototype?
Sorry for the silly question but I can't find
any link to read anything about this argument.
Best regards

Nope. The prototype of a variadic function must contain at least one
fixed parameter before the ellipsis. This is the definition of a
variadic function using the pre-ANSI <varargs.h> mechanism.

"man varargs" on the system this code was written for. If it's not a
Unix system, look up the documentation of the <varargs.h> header.
