A timespec structure is a standard structure found in the "C"/Unix world. It represents time as two fields in a structure, a seconds field and a microseconds field. Performing simple operations, such as addition and subtraction, is not completely trivial, so this file provides a set of standard manipulation routines.

Function Documentation

struct timespec TSS_from_wct (  WCT_time  wct  )

Converts a Wall Clock Time to a struct timespec. Parameters: wct  The Wall Clock Time to convert Returns: The TimeOut Value

struct timespec TSS_nsecsTOtodAdd (  unsigned int  delta  )

Computes the time specification by adding a number of nanoseconds to the current time. Parameters: delta  The number of microeconds to add to the current time. Return values: The  new time returned as a timespec structure.

struct timespec TSS_nsecxTOtodAdd (  long long int  delta  )

Computes the time specification by adding a number of nanoseconds to the current time. Parameters: delta  The number of microeconds to add to the current time. Return values: The  new time returned as a timespec structure.

struct timespec TSS_secsTOtodAdd (  unsigned int  delta  )

Computes the time specification by adding a number of seconds to the current time. Parameters: delta  The number of seconds to add to the current time. Return values: The  new time returned as a timespec structure.

struct timespec TSS_usecsTOtodAdd (  unsigned int  delta  )

Computes the time specification by adding a number of microseconds to the current time. Parameters: delta  The number of microeconds to add to the current time. Return values: The  new time returned as a timespec structure.
