Function
GLibsteal_fd
since: 2.70
Declaration [src]
static inline int
g_steal_fd (
int* fd_ptr
)
Description [src]
Sets fd_ptr to -1, returning the value that was there before.
Conceptually, this transfers the ownership of the file descriptor
from the referenced variable to the caller of the function (i.e.
‘steals’ the reference). This is very similar to g_steal_pointer(),
but for file descriptors.
On POSIX platforms, this function is async-signal safe
(see signal(7) and
signal-safety(7)), making it safe to call from a
signal handler or a GSpawnChildSetupFunc.
This function preserves the value of errno.
