The identifier given by dname has the type “cv-mod-list function, taking argument-declaration-list, and returning type decl-specifiers.”

Note that const, volatile, and many of the Microsoft-specific keywords can appear in cv-mod-list and in the declaration of the name. The following example shows two simple function declarations:

char *strchr( char *dest, char *src );
static int atoi( const char *ascnum ) const;
