GiD_fWriteCoordinates

int GiD_fWriteCoordinates(GiD_FILE fd, int id, double x, double y, double z);
int GiD_fWriteCoordinates2D(GiD_FILE fd, int id, double x, double y);

Description: Write a coordinate member at the current Coordinates Block.
If the mesh dimension is 2D then you can use GiD_fWriteCoordinates2D

Parameters:
GiD_FILE fd the file descriptor
int id
Node number identifier (starting from 1, is recommended to avoid jumps in the
numeration)
double x,double y,double z
Cartesian coordinates

Example:
C/C++

int id=1;
double x=3.5,y=1.5e-2,z=0;
GiD_fWriteCoordinates(fd,id,x,y,z);
