Description Usage Arguments Details Value Author(s) See Also Examples

Allows re-opening a previously opened VCF file.

1	vcf_reopen(vcffh)

vcffh

VCF file handle as returned by vcf_open

If a file handle was closed (vcf_close) or became stale (e.g. after an R crash), it can be reactivated with this function. Use .Call("VCF_reopen", vcffh ) to eliminate the overhead of using the R wrapper function.

Returns the reopened file handle.
