Filter incompat. mkostemp(3) flags on macOS 10.12
|
|
|
|
macOS Sierra introduces a mkostemp(3) function which is used when
|
|
present. Contrary to the GNUlib version of mkostemp(3) that was used
|
|
previously, this version fails with 'invalid argument' when flags other
|
|
than from a specified set are passed. From mktemp(3):
|
|
|
|
| The mkostemp() function is like mkstemp() but allows specifying
|
|
| additional open(2) flags (defined in <fcntl.h>). The permitted flags
|
|
| are O_APPEND, O_SHLOCK, O_EXLOCK and O_CLOEXEC.
