socket descriptor

[pralu]

can any one tell me what is socket descriptor in socket programming in c.

[jephthah]

in general terms (although not exactly precise), the "socket descriptor" is used like the "handle" for the socket, similar to a FILE * handle. int sd = socket(AF_INET, SOCK_STREAM, 0); where "sd" is the socket descriptor and, like a file handle, is then used to make additional calls to the socket like "connect" "read" "write" and "close"
