| |
| <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 –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> |
