The tevent call depth tracking functions
The call depth tracking consists of two parts.

Functions¶

int tevent_timeval_compare (const struct timeval *tv1, const struct timeval *tv2)
Compare two timeval values. struct timeval tevent_timeval_zero (void)
Get a zero timeval value. struct timeval tevent_timeval_current (void)
Get a timeval value for the current time. struct timeval tevent_timeval_set (uint32_t secs, uint32_t usecs)
Get a timeval structure with the given values. struct timeval tevent_timeval_until (const struct timeval *tv1, const struct timeval *tv2)
Get the difference between two timeval values. bool tevent_timeval_is_zero (const struct timeval *tv)
Check if a given timeval structure is zero. struct timeval tevent_timeval_add (const struct timeval *tv, uint32_t secs, uint32_t usecs)
Add the given amount of time to a timeval structure. struct timeval tevent_timeval_current_ofs (uint32_t secs, uint32_t usecs)
Get a timeval in the future with a specified offset from now. pid_t tevent_cached_getpid (void)
A cached version of getpid()

pid_t tevent_cached_getpid (void)¶

A cached version of getpid() We use getpid() in a lot a performance critical situations in order to check if caches are still valid in the current process.

Calling getpid() always add the cost of an additional syscall!

When tevent is build with pthread support, we already make use of pthread_atfork(), so it's trivial to use it maintain a cache for getpid().

Returns

struct timeval tevent_timeval_add (const struct timeval * tv, uint32_t secs, uint32_t usecs)¶

Add the given amount of time to a timeval structure.

Parameters

Returns

int tevent_timeval_compare (const struct timeval * tv1, const struct timeval * tv2)¶

Compare two timeval values.

Parameters

Returns

Compare two timeval values.

Return -1 if tv1 < tv2 Return 0 if tv1 == tv2 Return 1 if tv1 > tv2

struct timeval tevent_timeval_current (void)¶

Get a timeval value for the current time.

Returns

Get a timeval value for the current time.

struct timeval tevent_timeval_current_ofs (uint32_t secs, uint32_t usecs)¶

Get a timeval in the future with a specified offset from now.

Parameters

Returns

Get a timeval in the future with a specified offset from now.

bool tevent_timeval_is_zero (const struct timeval * tv)¶

Check if a given timeval structure is zero.

Parameters

Returns

Check if a given timeval structure is zero.

struct timeval tevent_timeval_set (uint32_t secs, uint32_t usecs)¶

Get a timeval structure with the given values.

Parameters

Returns

struct timeval tevent_timeval_until (const struct timeval * tv1, const struct timeval * tv2)¶

Get the difference between two timeval values.

Parameters

Returns

Get the difference between two timeval values.

struct timeval tevent_timeval_zero (void)¶

Get a zero timeval value.

Returns

Get a zero timeval value.
