ZIP_FILE_ADD(3)          BSD Library Functions Manual          ZIP_FILE_ADD(3)
NAME
     zip_file_add, zip_file_replace -- add file to zip archive or replace file
     in zip archive
LIBRARY
     libzip (-lzip)
SYNOPSIS
     #include <zip.h>
     zip_int64_t
     zip_file_add(zip_t *archive, const char *name, zip_source_t *source,
         zip_flags_t flags);
     int
     zip_file_replace(zip_t *archive, zip_uint64_t index,
         zip_source_t *source, zip_flags_t flags);
DESCRIPTION
     The function zip_file_add() adds a file to a zip archive, while
     zip_file_replace() replaces an existing file in a zip archive.  The argu-
     ment archive specifies the zip archive to which the file should be added.
     name is the file's name in the zip archive (for zip_file_add()), while
     index specifies which file should be replaced (for zip_file_replace()).
     The flags argument can be any combination of ZIP_FL_OVERWRITE with one of
     ZIP_FL_ENC_*:
     ZIP_FL_OVERWRITE      Overwrite any existing file of the same name.  For
                           zip_file_add only.
     ZIP_FL_ENC_GUESS      Guess encoding of name (default).
     ZIP_FL_ENC_UTF_8      Interpret name as UTF-8.
     ZIP_FL_ENC_CP437      Interpret name as code page 437 (CP-437).
     The data is obtained from the source argument, see zip_source(3).
     NOTE: zip_source_free(3) should not be called on a source after it was
     used successfully in a zip_file_add or zip_file_replace call.
RETURN VALUES
     Upon successful completion, zip_file_add() returns the index of the new
     file in the archive, and zip_file_replace() returns 0.  Otherwise, -1 is
     returned and the error code in archive is set to indicate the error.
EXAMPLES
           zip_source_t *s;
           const char *buf="teststring";
           if ((s=zip_source_buffer(archive, buf, sizeof(buf), 0)) == NULL ||
               zip_file_add(archive, name, s, ZIP_FL_ENC_UTF_8) < 0) {
               zip_source_free(s);
               printf("error adding file: %s\n", zip_strerror(archive));
           }
ERRORS
     zip_file_add() and zip_file_replace() fail if:
     [ZIP_ER_EXISTS]    There is already a file called name in the archive.
                        (Only applies to zip_file_add(), and only if
                        ZIP_FL_OVERWRITE is not provided).
     [ZIP_ER_INVAL]     source or name are NULL, or index is invalid.
     [ZIP_ER_MEMORY]    Required memory could not be allocated.
     [ZIP_ER_RDONLY]    Archive was opened in read-only mode.
