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
zip_file_add
only.ZIP_FL_ENC_GUESS
ZIP_FL_ENC_UTF_8
ZIP_FL_ENC_CP437
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.
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.
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)); }
