|ZIP_FILE_GET_COMMENT(3)||Library Functions Manual||ZIP_FILE_GET_COMMENT(3)|
const char *
zip_file_get_comment() function returns the comment for the file at position index in the zip archive. The name is in UTF-8 encoding unless
ZIP_FL_ENC_RAWwas specified (see below). This pointer should not be modified or free(3)'d, and becomes invalid when archive is closed. If lenp is not
NULL, the integer to which it points will be set to the length of the comment. If flags is set to
ZIP_FL_UNCHANGED, the original unchanged comment is returned.
Additionally, the following flags are supported:
- Return the unmodified comment as it is in the ZIP archive.
- (Default.) Guess the encoding of the comment in the ZIP archive and convert it to UTF-8, if necessary.
- Follow the ZIP specification for file names and extend it to file comments, expecting them to be encoded in CP-437 in the ZIP archive (except if it is a UTF-8 comment from the special extra field). Convert it to UTF-8.
RETURN VALUES¶Upon successful completion, a pointer to the comment is returned, or
NULLif there is no comment. In case of an error,
NULLis returned and the error code in archive is set to indicate the error.
zip_file_get_comment() fails if:
- index is not a valid file index in archive.
