SdfScanBig
Syntax int SdfScanBig (short fn, struct SDF_SCAN_BIG far *scanBig);
Returns an integer (short) of greater than zero, zero, or minus one. A return of greater than
zero indicates that an SDF_SCAN_BIG header was found (returns
SDF_SCAN_BIG_TYPE) or one was created from an SDF_SCAN_STRUCT
(returns SDF_SCAN_STRUCT_TYPE). A return of 0 indicates that no scan header
of any type was found. A return of
−1 indicates an error.
This function reads the scan 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_SCAN_BIG structure, where scanBig
is the pointer to the structure. If an SDF_SCAN_BIG record is not in the file, one will be created from
the SDF_SCAN_STRUCT record in the file.
