The mkstemp() function makes the same replacement to the template and creates the template file, mode 0600, returning a file descriptor opened for reading and writing. This avoids the race between testing for a file's existence and opening it for use.
The mkostemp() function is like mkstemp() but allows specifying additional open(2) flags (defined in <fcntl.h>). The permitted flags are O_APPEND, O_DIRECT, O_SHLOCK, O_EXLOCK, O_SYNC and O_CLOEXEC.
The mkstemps() and mkostemps() functions act the same as mkstemp() and mkostemp() respectively, except they permit a suffix to exist in the template. The template should be of the form /tmp/tmpXXXXXXsuffix. The mkstemps() and mkostemps() function are told the length of the suffix string.
The mkdtemp() function makes the same replacement to the template as in mktemp() and creates the template directory, mode 0700.
[ENOTDIR] | |
The pathname portion of the template is not an existing directory. | |
The mkostemp() and mkostemps() functions may also set errno to the following value:
[EINVAL] | |
The oflags argument is invalid. | |
The mkstemp(), mkostemp(), mkstemps(), mkostemps() and mkdtemp() functions may also set errno to any value specified by the stat(2) function.
The mkstemp(), mkostemp(), mkstemps() and mkostemps() functions may also set errno to any value specified by the open(2) function.
The mkdtemp() function may also set errno to any value specified by the mkdir(2) function.
The mkdtemp(), mkstemp() and mktemp() function prototypes are also available from <unistd.h>.
