<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This function is ripe for potential buffer overflow using a fixed buffer and sprintf(). I had a similar problem in libpri with the pri_dump_info_str() function. It can be solved in a similar way using a helper function like pri_snprintf().</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I will copy the function from libpri and will rewrite this one, but one question here.
Should i keep the function static inside isup.c or it is preferable to define it in ss7_internal.h and put it in ss7.c so it can be used in other places too if necessary?</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Keep it static. It is a helper function for isup_show_calls(). There is no other function that really needs that help.</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Done and also changed the function to void.</pre>
