NXC Version 1.2.1 r5
Convert string to integer.
Parses the string str interpreting its content as an integral number, which is returned as an int value.
The function first discards as many whitespace characters as necessary until the first non-whitespace character is found. Then, starting from this character, takes an optional initial plus or minus sign followed by as many numerical digits as possible, and interprets them as a numerical value.
The string can contain additional characters after those that form the integral number, which are ignored and have no effect on the behavior of this function.
If the first sequence of non-whitespace characters in str does not form a valid integral number, or if no such sequence exists because either str is empty or contains only whitespace characters, no conversion is performed.
