◆ efds

SlFdSet_t efds

This is not a class members so that including CC32xxWiFi.hxx does not pollute the namespace with simplelink APIs.

Definition at line 92 of file net_cc3220/CC32xxWiFi.cxx.

◆ fdHighest

int fdHighest

◆ rfds

static

This is not a class members so that including CC32xxWiFi.hxx does not pollute the namespace with simplelink APIs.

◆ slSockets

int16_t slSockets[SL_MAX_SOCKETS]

static

This is not a class members so that including CC32xxWiFi.hxx does not pollute the namespace with simplelink APIs.

slSockets keeps track of all the possible CC32x sockets. On the CC3200, SL_MAX_SOCKETS is 8. On the CC3220, SL_MAX_SOCKETS is 16. Unused slots will have a value of -1, which is initialized in the CC32xxWifi class constructor. If a socket becomes interesting (is added to a select() call list), it will be added to an open slot in slSockets by its CC32xx socket descriptor space value. When a socket is closed, it is removed from the from slSockets and the resulting empty slot is returned to a value of -1.

Note: not all socket descriptors will be added to slSockets for tracking. Only those sockets which are added to a select() call list will be tracked by slSockets.
