fdds_prev - fetch previouse field tag within a DDS structureSYNOPSIS#include <fdds.h> (fixed-format sources)#include <f90dds.h> (free-format sources) integer fdds_prev(bin_tag, field_tag)
DESCRIPTIONfdds_prev returns the tag associated with the field of the previous member or object from the member or object defined by field_tag within the current structure. A return value of -1 indicates field_tag is the first member or object.INPUTbin_tag is the tag associated with an open binary, previously obtained from fdds_open. It specifies a particular binary stream.field_tag is the tag associated with a particular field known by bin_tag. A value of "0" always refers to the entire trace field. OUTPUTThe return value is the field tag associate with the desired object or -1 if none found.SEE ALSOfdds_member Fetch field tag fdds_object Fetch object tag fdds_next Fetch next field tag fdds_parent Fetch parent field tag fdds_prime Fetch field prime tag AUTHORJerry Ehlers, BP America (May 2003) |
