# On some hosts (e.g., HP-UX 10.20, SunOS 4.1.4, Solaris 2.5.1), mkstemp has a
|
|
# silly limit that it can create no more than 26 files from a given template.
|
|
# Other systems lack mkstemp altogether.
|
|
# On OSF1/Tru64 V4.0F, the system-provided mkstemp function can create
|
|
# only 32 files per process.
|
|
# On some hosts, mkstemp creates files with mode 0666, which is a security
|
|
# problem and a violation of POSIX 2008.
|
|
# On systems like the above, arrange to use the replacement function.
