NAME

       zip_file_add, zip_file_replace - add file to zip archive or replace file in zip archive

LIBRARY

       libzip (-lzip)

SYNOPSIS

       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.
