Expand description

Reads a string of ASCII digits in the specified radix from the zero terminated str provided into z. For values of radix > 10, the letters A..Z or a..z are accepted. Letters are interpreted without respect to case.

Leading whitespace is ignored, and a leading + or - is interpreted as a sign flag. Processing stops when a NUL or any other character out of range for a digit in the given radix is encountered.

If the whole string was consumed, MP_OK is returned; otherwise MP_TRUNC. is returned.

Requires MP_MIN_RADIX <= radix <= MP_MAX_RADIX.
