Restriction | See Support for optional PV-WAVE modules to check if this function is available on your operating system. |
Usage
status = HDFPUTFILEANN (filename)
Input Parameters
filename—A string containing the name of the HDF file.
Return Value
status—The status of the function call, where:
SUCCEED (0)—Indicates success.FAIL (–1)—Indicates failure.Keywords
Description—A byte array that contains the description for the specified file. This byte array may require further processing later for display of the description.
Help—If present and nonzero, lists the usage for this routine.
Label—A string variable that contains the label for the specified file.
Usage—If present and nonzero, lists the usage for this routine. (Same as the Help keyword.)
Discussion
Multiple calls to HDFPUTFILEANN will cause additional labels/descriptions to be added in the file. There is no way known to overwrite an existing file label/description, other than to start writing a new file.
Example 1
hdf_init
@hdf_common
testfile = !Data_dir + '/raster8.hdf'
label = 'Put File Label (ID) Test'
status = HDFPUTFILEANN(testfile, Label=label)
IF (status EQ FAIL) THEN $
MESSAGE, 'Failed HDFPUTFILEANN with Label.'
Example 2
hdf_init
@hdf_common
testfile = !Data_dir + '/raster8.hdf'
desc = BYTE ('Put File Description Test')status = HDFPUTFILEANN(testfile, Description=desc)
IF (status EQ FAIL) THEN $
MESSAGE, 'Failed HDFPUTFILEANN with Description.'
