What can cause a Resource temporarily unavailable
error on a socket send()
command? The socket is setup as AF_UNIX, SOCK_STREAM
. It works most of the time, but occasionally gets this error. The receiving end of the socket appears to be working properly.
I know this isn't very detailed, but I'm just looking for general ideas. Thanks!
"Resource temporarily unavailable"
is the error message corresponding to EAGAIN
, which means that the operation would have blocked but nonblocking operation was requested. For send()
, that could be due to any of:
fcntl()
; orMSG_DONTWAIT
flag to send()
; orSO_SNDTIMEO
socket option.If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
