zip_source_begin_write(3) Library Functions Manual zip_source_begin_write(3)
NAME
zip_source_begin_write, zip_source_begin_write_cloning - prepare zip
source for writing
LIBRARY
libzip (-lzip)
SYNOPSIS
#include <zip.h>
int
zip_source_begin_write(zip_source_t *source);
int
zip_source_begin_write_cloning(zip_source_t *source,
zip_uint64_t offset);
DESCRIPTION
The functions zip_source_begin_write() and
zip_source_begin_write_cloning() prepare source for writing. Usually
this involves creating temporary files or allocating buffers.
zip_source_begin_write_cloning() preserves the first offset bytes of the
original file. This is done efficiently, and writes to source won't
overwrite the original data until zip_commit_write() is called.
RETURN VALUES
Upon successful completion 0 is returned. Otherwise, -1 is returned and
the error information in source is set to indicate the error.
