skip.connection.bytes: Skip over bytes of a connection, transparently handling gzip.

In freesurferformats: Read and Write 'FreeSurfer' Neuroimaging File Formats

Skip over bytes of a connection, transparently handling gzip.

Description

Skips forward from the current position of the connection. R cannot seek on a gzfile connection (the underlying gzseek() fails with 'invalid or incomplete compressed data' and only warns instead of failing loudly), so compressed connections are skipped by reading and discarding the bytes instead.

Usage

skip.connection.bytes(con, num_bytes, gzipped, filepath = "")

Arguments

con	a connection opened in binary read mode.
num_bytes	numeric, the number of bytes to skip, relative to the current position of the connection.
gzipped	logical, whether the connection is a gzfile connection, as reported by is.gzip.file.
filepath	character string, used in error messages only.

Value

TRUE, invisibly.
