RtAtoi

RtAtoi converts a given string value to an integer.

Syntax

INT RtAtoi(
    LPCSTR lpString
);

Parameters

lpString

The source character string.

Return Values

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
• INT_MIN if the converted value is too small for the return variable range

Remarks

RtAtoi is similar to atoi, but RtAtoi does not require the C runtime library and can work with any combination of run-time libraries.

This function supports decimal digits only, and does not allow leading whitespace or signs.
