|
byteswap |
- |
Optional. An integer. Swap the order of the bytes to write:
|
||||
|
series |
- |
Optional. A series, the values to write. Defaults to the current Window. |
Nothing.
fopen("test.bin", "wb")
fwriteb("test.bin", sint, {1..5})
fclose("test.bin")
a = readb("test.bin", sint)
a == {1, 2, 3, 4, 5}
FWRITEB writes 5 signed integer values to the file. READB returns the values as a series in variable a.
File must be opened with FOPEN before using FWRITEB. FWRITEB operates like WRITEB once FOPEN is used to open the file.
Use "wb" to open the binary file in write mode.
