StrToInt
int StrToInt (const char string[], int *integerValue);
Purpose
Attempts to convert a nul–terminated string to an integer value.
If the bytes in the nul–terminated string contain a valid ASCII decimal representation of an integer value, and there are no extraneous non–white–space characters in the string, this function returns 1. Otherwise, this function returns 0.
This function is similar to the C library strtol function except in how extraneous characters are treated.
