Function Documentation

swap_alm_doubles()

void swap_alm_doubles

(

ALM *

p

)

Swap the "double" fields in an ALM structure.

See comments for swap_double

Parameters

[in,out]

p

Pointer to an ALM structure to be converted

See also

swap_double

swap_double()

void swap_double

(

double *

p

)

Swap the bytes of a single variable of type "double".

The memory layout of a "double" on Meinberg bus level devices and computers usually differs. This function can be used to fix this and is usually called from inside API functions, if required.

Parameters

[in,out]

p

Pointer to a "double" to be swapped

swap_alm_doubles

swap_utc_doubles

swap_iono_doubles

swap_eph_doubles()

void swap_eph_doubles

(

EPH *

p

)

Swap the "double" fields in an EPH structure.

See comments for swap_double

Parameters

p

Pointer to an EPH structure to be converted
