Thread-safe conversion of a time_t value to Coordinated Universal Time (UTC).
#include <extras/extras_time.h> struct tm * gmtime_r(const time_t *time, struct tm * st);
time
A pointer to a time value.
st
A pointer to a time structure.
This function provides the same service as gmtime(). Unlike gmtime(), this function requires that the caller provides the storage for the tm structure. The gmtime_r() function always returns the value of st.
This function may require extra library support.
This facility is not specified in the ISO/IEC standards. It is an EWL extension of the standard libraries.
