char * strophe_strdup | ( | const xmpp_ctx_t * | ctx, |
const char * | 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.
ctx | a Strophe context object |
s | a string |
char * strophe_strndup | ( | const xmpp_ctx_t * | ctx, |
const char * | s, | ||
size_t | len | ||
) |
Duplicate a string with a maximum length.
This function replaces the standard strndup library call with a version that uses the Strophe context object's allocator.
ctx | a Strophe context object |
s | a string |
len | the maximum length of the string to copy |
len
symbols of the original string or NULL on error char * strophe_strtok_r | ( | char * | s, |
const char * | delim, | ||
char ** | saveptr | ||
) |
strtok_r(3) implementation.
This function has appeared in POSIX.1-2001, but not in C standard. For example, visual studio older than 2005 doesn't provide strtok_r() nor strtok_s().
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.
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.
t1 | first time stamp |
t2 | second time stamp |
void disconnect_mem_error | ( | xmpp_conn_t * | 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.
conn | a Strophe connection object |
int string_to_ul | ( | const char * | s, |
unsigned long * | ul | ||
) |
void hex_encode | ( | char * | writebuf, |
void * | readbuf, | ||
size_t | len | ||
) |
