LIBRARY

libzip -lzip)  

SYNOPSIS

In zip.h Ft zip_int64_t Fn zip_file_add zip_t *archive const char *name zip_source_t *source zip_flags_t flags Ft int Fn zip_file_replace zip_t *archive zip_uint64_t index zip_source_t *source zip_flags_t flags  

DESCRIPTION

The function Fn zip_file_add adds a file to a zip archive, while Fn 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 Fn zip_file_add ) , while index specifies which file should be replaced (for Fn 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 C-437 and UT-8 are recognized.)

ZIP_FL_ENC_UTF_8

Interpret name as UT-8.

ZIP_FL_ENC_CP437

Interpret name as code page 437 (C-437).

The data is obtained from the source argument, see zip_source5.

NOTE zip_source_free3 should not be called on a source after it was used successfully in a zip_file_add or zip_file_replace call.

Please also note that when using zip_replace the target file's extra field information will be deleted since this usually is dependent on the file contents. If you want to keep them, query them beforehand with zip_file_extra_field_get3 and restore them after zip_replace with zip_file_extra_field_set3.  

RETURN VALUES

Upon successful completion, Fn zip_file_add returns the index of the new file in the archive, and Fn 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: %sn", zip_strerror(archive));
}
