* getaddrinfo.h
|
|
* Support getaddrinfo() on platforms that don't have it.
|
|
*
|
|
* Note: we use our own routines on platforms that don't HAVE_STRUCT_ADDRINFO,
|
|
* whether or not the library routine getaddrinfo() can be found. This
|
|
* policy is needed because on some platforms a manually installed libbind.a
|
|
* may provide getaddrinfo(), yet the system headers may not provide the
|
|
* struct definitions needed to call it. To avoid conflict with the libbind
|
|
* definition in such cases, we rename our routines to pg_xxx() via macros.
|
|
*
|
|
|
|
in lib/replace we use rep_xxx()
|
|
|
|
* This code will also work on platforms where struct addrinfo is defined
|
|
* in the system headers but no getaddrinfo() can be located.
