Converts a string to a 4-byte integer (machine dependent).

The conversion failed. |
Usage
Important: The function takes a machine-dependent long pointer (4 bytes on 32-bit and 8
bytes on 64-bit architectures), but the function converts to a 4-byte integer (overflow error
may occur if string does not represent a valid 2 byte integer).
