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.
