- Method
__handle_sprintf_format
type(mixed) __handle_sprintf_format(string attr, string fmt, type(mixed) arg_type, type(mixed) cont_type)
- Description
Type attribute handler for "sprintf_format".
- Parameter attr
Attribute to handle, either "sprintf_format"
or "strict_sprintf_format".
- Parameter fmt
Sprintf-style formatting string to generate type information from.
- Parameter arg_type
Declared type of the fmt argument (typically string).
- Parameter cont_type
Continuation function type after the fmt argument. This is
scanned for the type attribute "sprintf_args" to
determine where the remaining arguments to sprintf() will
come from.
This function is typically called from
PikeCompiler()->apply_attribute_constant() and is used to perform
stricter compile-time argument checking of sprintf() -style functions.
It currently implements two operating modes depending on the value of
attr :
| "strict_sprintf_format" | The formatting string fmt is known to always be passed to
sprintf() .
|
| "sprintf_format" | The formatting string fmt is passed to sprintf() only
if there are "sprintf_args".
