RtAtoi converts a given string value to an integer.

Syntax

INT RtAtoi(
    [in]    LPCSTR lpString
);

Parameters

[in] lpString

The source character string.

Return Value

On success the function returns:

• An INT value produced by the conversion

On failure the function returns:

• Zero if the input cannot be converted
• INT_MAX if the converted value is too large for the return variable range

RtAtoi is like atoi, but RtAtoi does not require the C Runtime library and can work with any combination of runtime libraries.
