## Detailed Description

Internally used utility functions.

## Macro Definition Documentation

## ◆ xmpp_min

#define xmpp_min | ( |  | x,
|  |  | y
| ) |  | ((x) < (y) ? (x) : (y))

## Function Documentation

## ◆ xmpp_strtok_r()

char* xmpp_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().

## ◆ time_stamp()

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

## ◆ time_elapsed()

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

  t1 | first time stamp
  t2 | second time stamp

Returns
  number of milliseconds between the stamps
