NAME

       ms_splitsrcname - Split source names into the SEED naming nomenclature.

SYNOPSIS

       #include <libmseed.h>

       char  *ms_splitsrcname ( char *srcname, char *net, char * sta,
                                char * loc, char *chan, char *qual );

DESCRIPTION

       The  ms_splitsrcname  routine  parses  SEED  channel  naming  components from a source name string in the
       following format:

       "NET_STA_LOC_CHAN[_QUAL]"

       The first four components are required to uniquely identify a SEED channel, generally  these  are  always
       present in a srcname.  The Quality code is normally optional in a source name.

       The arguments for the first four components (net, sta, loc & chan) are treated as strings but the quality
       code (qual) is treated as a pointer to a single character.

       Memory for the requested component strings must already be allocated.  If a component pointer is NULL  it
       will not be parsed from the string.

       Source names in the expected format are created, for example, by the ms_recsrcname(3), msr_srcname(3) and
       mst_srcname(3) routines.

LOCATION IDS AND SPACES

       The source name should never include spaces.  The fixed format nature of SEED data records leads to blank
       or  unused  location  IDs  represented  by  spaces,  in  a  source name such blank location IDs should be
       collapsed to nothing in the resulting sources names.  A blank location ID is parsed from a source name as
       an empty string (not two spaces).

EXAMPLES

       This  usage  will  result  in  net="IU",  sta="ANMO", loc="00", chan="BHZ" and qual will remain unchanged
       (because it was not contained in the input srcname):

       ms_splitsrcname("IU_ANMO_00_BHZ", net, sta, loc, chan, qual);

       This usage will limit the parsing to only the network and station components with net="IU", sta="ANMO":

       ms_splitsrcname("IU_ANMO_00_BHZ", net, sta, NULL, NULL, NULL);

       The following usage illustrates a blank location ID and included quality code:

       ms_splitsrcname("IU_ANMO__BHZ_Q", net, sta, loc, chan, qual);

       The result is:

       net = "IU"
       sta = "ANMO"
       loc = ""
       chan = "BHZ"
       qual = 'Q'

RETURN VALUES

       Return 0 on success and -1 on error.
