cqgrecord -- get a record from the catalog results
.ih
SYNOPSIS
stat = cq_grecord (res, buf, maxch, recno)
.nf
pointer res # the results descriptor
char buf # the output buffer
int maxch # the maximum size of the output buffer
int recno # the record to be fetched
.fi
.ih
ARGUMENTS
.ls res
The results descriptor.
.le
.ls buf
The buffer containing the returned record.
.le
.ls maxch
The maximum size of the output buffer.
.le

DESCRIPTION
Cq_grecord returns the requested record. Cq_grecord is an integer function
which returns BOF, the number of characters in the record, or EOF as
its function value.
.ih
NOTES
In most cases allocating a buffer size that is SZ_LINE chars long
will be adequate to hold the output record. If the integer results parameter
CQRECSIZE is defined, i.e. non-zero, then an output buffer CQRECSIZE chars
long can be allocated.
