  const s: string;

  const fmt: string;

  const Pointers: array of Pointer

):Integer;

Description

SSCanF scans the string S for the elements specified in Fmt, and returns the elements in the pointers in Pointers. The Fmt can contain placeholders of the form %X where X can be one of the following characters:

d
Placeholder for a decimal number.
f
Placeholder for a floating point number (an extended)
s
Placeholder for a string of arbitrary length.
c
Placeholder for a single character

The Pointers array contains a list of pointers, each pointer should point to a memory location of a type that corresponds to the type of placeholder in that position:

d
A pointer to an integer.
f
A pointer to an extended.
s
A pointer to an ansistring.
c
A pointer to a single character.

Errors

No error checking is performed on the type of the memory location.
