ZIP_FOPEN(3) Library Functions Manual ZIP_FOPEN(3) NAME zip_fopen, zip_fopen_index - open file in zip archive for reading LIBRARY libzip (-lzip) SYNOPSIS #include <zip.h> struct zip_file * zip_fopen(struct zip *archive, const char *fname, zip_flags_t flags); struct zip_file * zip_fopen_index(struct zip *archive, zip_uint64_t index, zip_flags_t flags); DESCRIPTION The zip_fopen() function opens the file name fname in archive. The flags argument specifies how the name lookup should be done, according to the values are described in zip_name_locate(3). Also, the following values may be or'ed to it. ZIP_FL_COMPRESSED Read the compressed data. Otherwise the data is uncompressed by zip_fread(). ZIP_FL_UNCHANGED Read the original data from the zip archive, ignoring any changes made to the file. The zip_fopen_index() function opens the file at position index. If encrypted data is encountered, the functions call zip_fopen_encrypted(3) or zip_fopen_index_encrypted(3) respectively, using the default password set with zip_set_default_password(3). RETURN VALUES Upon successful completion, a struct zip_file pointer is returned. Otherwise, NULL is returned and the error code in archive is set to indicate the error. ERRORS [ZIP_ER_CHANGED] The file data has been changed. [ZIP_ER_COMPNOTSUPP] The compression method used is not supported. [ZIP_ER_ENCRNOTSUPP] The encryption method used is not supported. [ZIP_ER_MEMORY] Required memory could not be allocated. [ZIP_ER_NOPASSWD] The file is encrypted, but no password has been provided. [ZIP_ER_READ] A file read error occurred. [ZIP_ER_SEEK] A file seek error occurred. [ZIP_ER_WRONGPASSWD] The provided password does not match the password used for encryption. Note that some incorrect passwords are not detected by the check done by zip_fopen(). [ZIP_ER_ZLIB] Initializing the zlib stream failed. The function zip_fopen() may also fail and set zip_err for any of the errors specified for the routine zip_name_locate(3). The function zip_fopen_index() may also fail with ZIP_ER_INVAL if index is invalid.
