<p><font size=+1><b>DESCRIPTION </b></font><br>
<table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td>
<i>Opentemp</i> replaces <i>template</i> by a unique file name, and returns
the address of the template. The template should look like a file
name with eleven trailing <tt><font size=+1>X</font></tt>s. The <tt><font size=+1>X</font></tt>s are replaced by a letter
followed by the current process id. Letters from <tt><font size=+1>a</font></tt> to <tt><font size=+1>z</font></tt> are tried
until the name of a file that does not yet exist (see <a href="../man2/access.html"><i>access</i>(2)</a>)
is
generated. <i>Opentemp</i> then creates the file for reading and writing
and returns the file descriptor.
<table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
If no such name can be generated, <i>opentemp</i> returns &ndash;1.
<table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
<i>Opentemp</i> avoids races. Two simultaneous calls to <i>opentemp</i> will
never return the same name.<br>
