Lets add<br>bssgp_rim_ri_name() and bssgp_rim_ri_name_buf() to make printing a<br>routing identifier easier.<br><br>Change-Id: Idca6bdccffe663aea71a0183ca3ea5bb5b59e702<br>Related: SYS#5103<br>---<br>M include/osmocom/gprs/gprs_bssgp_rim.h<br>M src/gb/gprs_bssgp_rim.c<br>M src/gb/libosmogb.map<br>3 files changed, 64 insertions(+), 0 deletions(-)<br><br></pre><pre style="font-family: monospace,monospace; white-space: pre-wrap;">git pull ssh://gerrit.osmocom.org:29418/libosmocore refs/changes/38/22438/1</pre><pre style="font-family: monospace,monospace; white-space: pre-wrap;"><span>diff --git a/include/osmocom/gprs/gprs_bssgp_rim.h b/include/osmocom/gprs/gprs_bssgp_rim.h</span><br><span>index 0810c8e..432805c 100644</span><br><span>--- a/include/osmocom/gprs/gprs_bssgp_rim.h</span><br><span>+++ b/include/osmocom/gprs/gprs_bssgp_rim.h</span><br><span>@@ -64,6 +64,8 @@</span><br><span> * address type (discr) of variable length. */</span><br><span> #define BSSGP_RIM_ROUTING_INFO_MAXLEN 14</span><br><span> </span><br><span style="color: hsl(120, 100%, 40%);">+char *bssgp_rim_ri_name_buf(char *buf, size_t buf_len, const struct bssgp_rim_routing_info *ri);</span><br><span style="color: hsl(120, 100%, 40%);">+char *bssgp_rim_ri_name(const struct bssgp_rim_routing_info *ri);</span><br><span> int bssgp_parse_rim_ri(struct bssgp_rim_routing_info *ri, const uint8_t *buf, unsigned int len);</span><br><span> int bssgp_create_rim_ri(uint8_t *buf, const struct bssgp_rim_routing_info *ri);</span><br><span> </span><br><span>diff --git a/src/gb/gprs_bssgp_rim.c b/src/gb/gprs_bssgp_rim.c</span><br><span>index 844268a..d89e526 100644</span><br><span>--- a/src/gb/gprs_bssgp_rim.c</span><br><span>+++ b/src/gb/gprs_bssgp_rim.c</span><br><span>@@ -146,6 +146,66 @@</span><br><span> return len;</span><br><span> }</span><br><span> </span><br><span style="color: hsl(120, 100%, 40%);">+/*!
