22 The function zip_file_add() adds a file to a zip archive, while
23 zip_file_replace() replaces an existing file in a zip archive. The argu‐
24 ment archive specifies the zip archive to which the file should be added.
25 name is the file's name in the zip archive (for zip_file_add()), while
26 index specifies which file should be replaced (for zip_file_replace()).
27 The flags argument can be any combination of ZIP_FL_OVERWRITE with one of
28 ZIP_FL_ENC_*:
29
30 ZIP_FL_OVERWRITE Overwrite any existing file of the same name. For
31 zip_file_add only.
32
33 ZIP_FL_ENC_GUESS Guess encoding of name (default).
34
35 ZIP_FL_ENC_UTF_8 Interpret name as UTF-8.
36
37 ZIP_FL_ENC_CP437 Interpret name as code page 437 (CP-437).
38 The data is obtained from the source argument, see zip_source(3).
39
40 NOTE: zip_source_free(3) should not be called on a source after it was
41 used successfully in a zip_file_add or zip_file_replace call.
42
44 Upon successful completion, zip_file_add() returns the index of the new
45 file in the archive, and zip_file_replace() returns 0. Otherwise, -1 is
46 returned and the error code in archive is set to indicate the error.
47
49 zip_source_t *s;
50 const char *buf="teststring";
51
52 if ((s=zip_source_buffer(archive, buf, sizeof(buf), 0)) == NULL ||
53 zip_file_add(archive, name, s, ZIP_FL_ENC_UTF_8) < 0) {
54 zip_source_free(s);
55 printf("error adding file: %s\n", zip_strerror(archive));
56 }
57
59 zip_file_add() and zip_file_replace() fail if:
60
61 [ZIP_ER_EXISTS] There is already a file called name in the archive.
62 (Only applies to zip_file_add(), and only if
63 ZIP_FL_OVERWRITE is not provided).
64
65 [ZIP_ER_INVAL] source or name are NULL, or index is invalid.
66
67 [ZIP_ER_MEMORY] Required memory could not be allocated.
68
69 [ZIP_ER_RDONLY] Archive was opened in read-only mode.
