The pam_getenvlist function returns a complete copy of the PAM
environment as associated with the handle pamh. The PAM environment
variables represent the contents of the regular environment variables
of the authenticated user when service is granted.
The format of the memory is a malloc()'d array of char pointers, the
last element of which is set to NULL. Each of the non-NULL entries in
this array point to a NUL terminated and malloc()'d char string of
the form: "name=value".
It should be noted that this memory will never be free()'d by libpam.
Once obtained by a call to pam_getenvlist, it is the responsibility
of the calling application to free() this memory.
It is by design, and not a coincidence, that the format and contents
of the returned array matches that required for the third argument of
the execle(3) function call.
