/*
|
|
* Curl_gethostname() is a wrapper around gethostname() which allows
|
|
* overriding the host name that the function would normally return.
|
|
* This capability is used by the test suite to verify exact matching
|
|
* of NTLM authentication, which exercises libcurl's MD4 and DES code
|
|
* as well as by the SMTP module when a hostname is not provided.
|
|
*
|
|
* For libcurl debug enabled builds host name overriding takes place
|
|
* when environment variable CURL_GETHOSTNAME is set, using the value
|
|
* held by the variable to override returned host name.
|
|
*
|
|
* Note: The function always returns the un-qualified hostname rather
|
|
* than being provider dependent.
|
|
*
|
|
* For libcurl shared library release builds the test suite preloads
|
|
* another shared library named libhostname using the LD_PRELOAD
|
|
* mechanism which intercepts, and might override, the gethostname()
|
|
* function call. In this case a given platform must support the
|
|
* LD_PRELOAD mechanism and additionally have environment variable
|
|
* CURL_GETHOSTNAME set in order to override the returned host name.
|
|
*
|
|
* For libcurl static library release builds no overriding takes place.
