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.
