.SH DESCRIPTION
|
|
.B pcap_list_tstamp_types()
|
|
is used to get a list of the supported time stamp types of the interface
|
|
associated with the pcap descriptor.
|
|
.B pcap_list_tstamp_types()
|
|
allocates an array to hold the list and sets
|
|
.I *tstamp_typesp
|
|
to point to the array.
|
|
See
|
|
.BR pcap-tstamp (@MAN_MISC_INFO@)
|
|
for a list of all the time stamp types.
|
|
.PP
|
|
The caller is responsible for freeing the array with
|
|
.BR pcap_free_tstamp_types() ,
|
|
which frees the list pointed to by
|
|
.IR tstamp_types .
|
|
.SH RETURN VALUE
|
|
.B pcap_list_tstamp_types()
|
|
returns the number of time stamp types in the array on success and
|
|
.B PCAP_ERROR
|
|
on failure.
|
|
A return value of zero means that you cannot specify a time stamp type;
|
|
you are limited to the capture device's default time stamp type.
|
|
If
|
|
.B PCAP_ERROR
|
|
is returned,
|
|
.B pcap_geterr()
|
|
or
|
|
.B pcap_perror()
|
|
may be called with
|
|
.I p
|
|
as an argument to fetch or display the error text.
