fr_bio_fd_errno_retry()

static bool fr_bio_fd_errno_retry ( fr_bio_fd_t *  my, ssize_t *  rcode_p, int *  tries_p, bool  is_write  )

inlinestatic

Turn a failed read / write into a bio return code.

Only called when the syscall failed, i.e. when rcode is negative.

Parameters

	my	the FD bio.
[in,out]	rcode_p	in: the failed syscall return code. out: what to return to the application.
[in,out]	tries_p	how many times we have retried on EINTR.
	is_write	true for the write path, false for the read path.

Returns

• false return *rcode_p to the application.
• true the syscall was interrupted, redo it.
