!!DESCRIPTION |
|
|
24 |
|
|
|
25 |
|
|
|
26 |
The __tmpnam()__ function returns a pointer to a string |
|
|
27 |
that is a valid filename, and such that a file with this |
|
|
28 |
name did not exist at some point in time, so that naive |
|
|
29 |
programmers may think it a suitable name for a temporary |
|
|
30 |
file. If the argument ''s'' is NULL this name is |
|
|
31 |
generated in an internal static buffer and may be |
|
|
32 |
overwritten by the next call to __tmpnam()__. If ''s'' |
|
|
33 |
is not NULL, the name is copied to the character array (of |
|
|
34 |
length at least ''L_tmpnam'') pointed at by ''s'' and |
|
|
35 |
the value ''s'' is returned in case of |
|
|
36 |
success. |
|
|
37 |
|
|
|
38 |
|
|
|
39 |
The path name that is created, has a directory prefix |
|
|
40 |
''P_tmpdir''. (Both ''L_tmpnam'' and ''P_tmpdir'' |
|
|
41 |
are defined in '''', just like the TMP_MAX |
|
|
42 |
mentioned below.) |
|
|
43 |
!!RETURN VALUE |
|
|
44 |
|
|
|
45 |
|
|
|
46 |
The __tmpnam()__ function returns a pointer to a unique |
|
|
47 |
temporary filename, or NULL if a unique name cannot be |
|
|
48 |
generated. |
|
|

!!NOTES |
|
|
54 |
|
|
|
55 |
|
|
|
56 |
Portable applications that use threads cannot call |
|
|
57 |
__tmpnam()__ with NULL parameter if either |
|
|
58 |
_POSIX_THREAD_SAFE_FUNCTIONS or _POSIX_THREADS is |
|
|
59 |
defined. |
|
|
60 |
|
|
|
61 |
|
|
|
62 |
The __tmpnam()__ function generates a different string |
|
|
63 |
each time it is called, up to TMP_MAX times. If it is called |
|
|
64 |
more than TMP_MAX times, the behaviour is implementation |
|
|
65 |
defined. |
|
|
66 |
!!BUGS |
|
|
67 |
|
|
|
68 |
|
|
|
69 |
Never use this function. Use tmpfile(3) |
|
|
70 |
instead. |
