A convenience function for converting a string to a signed number.
This function assumes that str contains only a number of the given
base that is within inclusive bounds limited by min and max. If
this is true, then the converted number is stored in out_num. An
empty string is not a valid input. A string with leading or
trailing whitespace is also an invalid input.
base can be between 2 and 36 inclusive. Hexadecimal numbers must
not be prefixed with "0x" or "0X". Such a problem does not exist
for octal numbers, since they were usually prefixed with a zero
which does not change the value of the parsed number.
Parsing failures result in an error with the G_NUMBER_PARSER_ERROR
domain. If the input is invalid, the error code will be
G_NUMBER_PARSER_ERROR_INVALID. If the parsed number is out of
bounds - G_NUMBER_PARSER_ERROR_OUT_OF_BOUNDS.
See g_ascii_strtoll() if you have more complex needs such as
parsing a string which starts with a number, but then has other
characters.
