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 argument 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).

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, buffer, 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.
