ClientInfoExtFree()

QNX SDP8.0C Library ReferenceAPIDeveloper

Free the structure used for extended information about a client connection

Synopsis:

#include <sys/neutrino.h>

int ClientInfoExtFree( struct _client_info ** info );

Arguments:

info: The address of a pointer to the _client_info structure that you want to free. This address can refer to a NULL pointer; in this case, the call has no effect.

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Description:

This call frees the memory allocated by a call to ConnectClientInfoExt().

Returns:

0, or -1 if an error occurred (errno is set).

Classification:

QNX OS


Safety:
Cancellation point	No
Signal handler	Yes
Thread	Yes
