* mtime.h: high resolution time management functions
|
|
* This header provides portable high precision time management functions,
|
|
* which should be the only ones used in other segments of the program, since
|
|
* functions like gettimeofday() and ftime() are not always supported.
|
|
* Most functions are declared as inline or as macros since they are only
|
|
* interfaces to system calls and have to be called frequently.
|
|
* 'm' stands for 'micro', since maximum resolution is the microsecond.
|
|
* Functions prototyped are implemented in interface/mtime.c.
