Creates a binary file in raw C block I/O format for a numeric data type.
procedure cbinwrite ( filename  : string, var : numeric )
Name of C binary file to open. May include an absolute or relative path to the file.var
A numeric variable of any dimensionality.
The cbinwrite function is used to create a binary data file from a variable of type numeric. By default, the elements of value are written to the file in row x column order using the machine's native binary format. To force the byte order to be written as big-endian or little-endian, see the "WriteByteOrder" option in the setfileoption procedure.
; ; Write a C binary file called "tmp_file_x" with six elements. ; x = (/10.,20.,30.,40.,50.,60./) cbinwrite("tmp_file_x",x) ; ; Read the file back in. "y" will be an array of length 6. ; y = cbinread("tmp_file_x",-1,"float") print(y) ; ; Read the same file, only this time formatting it as a 2 x 3 array. ; z = cbinread("tmp_file_x",(/2,3/),"float") print(z)
From ncl-talk: I am using 'cbinwrite' to output some binary data to a file. Since I am writing data in a loop, I found that cbinwrite will overwrite the previous data every time. Does anybody know how to write the data in the file without overwriting?
cbinwrite("file.bin",data) do i = 1, number_of_writes -1 newdata = .... cbinwrite("tmp.bin",newdata) system("cat tmp.bin >> file.bin") end do
