Function Documentation

char* xmpp_strdup ( const xmpp_ctx_t *const  ctx,
const char *const  s 
)

implement our own strdup that uses the ctx allocator

Duplicate a string. This function replaces the standard strdup library call with a version that uses the Strophe context object's allocator.

Parameters:
ctxa Strophe context object
sa string
Returns:
a new allocates string with the same data as s or NULL on error
uint64_t time_stamp ( void  )

Return an integer based time stamp.

This function uses gettimeofday or timeGetTime (on Win32 platforms) to compute an integer based time stamp. This is used internally by the event loop and timed handlers.

Returns:
an integer time stamp
uint64_t time_elapsed ( uint64_t  t1,
uint64_t  t2 
)

Get the time elapsed between two time stamps.

This function returns the time elapsed between t1 and t2 by subtracting t1 from t2. If t2 happened before t1, the result will be negative. This function is used internally by the event loop and timed handlers.

Parameters:
t1first time stamp
t2second time stamp
Returns:
number of milliseconds between the stamps
void disconnect_mem_error ( xmpp_conn_t *const  conn)

Disconnect the stream with a memory error.

This is a convenience function used internally by various parts of the Strophe library for terminating the connection because of a memory error.

Parameters:
conna Strophe connection object
