Since BIND 9 headers are not longer public, there's no reason to keep the ISC_LANG_BEGINDECL and ISC_LANG_ENDDECL macros to support including them from C++ projects.

|
* The base is interpreted

*\li 'string' points to a null-terminated string
|
|
*\li 0 <= 'base' <= 36

|
* Returns:
|
|
*\li #ISC_R_SUCCESS
|
|
*\li #ISC_R_BADNUMBER The string is not numeric (in the given base)
|
|
*\li #ISC_R_RANGE The number is not representable as the requested type.
