SdfFileHdr
Syntax int SdfFileHdr (short fn, struct SDF_FILE_HDR far *fileHdr);
Returns an integer(short) of zero or minus one. A return of 0 indicates no error; a return of
-1 indicates an error.
This function reads the file-header information from an open SDF file, where fn is the number of the open
SDF file (for details, see SdfOpen). The information is put in the SDF_FILE_HDR structure, where
fileHdr is the pointer to the structure.
The SDF file header record contains information such as the application (instrument) that created it, the
time stamp, the index of all other types of records in the file and the offsets of those records from the
beginning of the file.
