NXC Version 1.2.1 r5
Convert string to unsigned long integer.
Parses the C string str interpreting its content as an unsigned integral number of the specified base, which is returned as an unsigned long 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 as many characters as possible that are valid following a syntax that depends on the base parameter, and interprets them as a numerical value. A string containing the rest of the characters following the integer representation in str is stored in endptr.
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.
|str||String containing the representation of an unsigned integral number.|
|endptr||Reference to a string, whose value is set by the function to the remaining characters in str after the numerical value.|
|base||Optional and ignored if specified.|
