E.164 Telephone Number Type

WARNING: This is an ALPHA release. Do not run this software in production.

E.164 is a recommendation by the International Telecommunication Union (ITU) for international telephone numbers. The E164 type provides a convenient method of storing international telephone numbers consistent with the E.164 recommendation. In particular,

  • Country code validation
  • Rudimentary format checking
    • Number consists of proper + prefix followed by digits.
    • Minimum and maximum length checking for corresponding E.164 Type

The E164 type does not check that the number is consistent with formats specific to particular national standards: formats vary by country. (Support for national format checking may be added in a future release.)

TODO

  • Add ENUM output (and possibly input) functions
  • Properly handle error conditions.
  • Fix issues raising compiler warnings: e164.c: In function 'e164_in': e164.c:146: warning: 'theNumber' may be used uninitialized in this function e164.c:156: warning: control reaches end of non-void function e164_base.c: In function 'e164In': e164_base.c:553: warning: 'theNumber' may be used uninitialized in this function e164_base.c:561: warning: control reaches end of non-void function
  • Fix all other FIXMEs in code :)
