ZIP_FILE_ADD(3) FreeBSD 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 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). (Only CP-437 and UTF-8 are recognized.)
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_ER_MEMORY] Required memory could not be allocated.
[ZIP_ER_RDONLY] Archive was opened in read-only mode.
