ZIP_SET_DEFAULT_PASSWORD(3)				     Library Functions Manual				       ZIP_SET_DEFAULT_PASSWORD(3)

NAME

       zip_set_default_password - set default password for encrypted files in zip

LIBRARY

       libzip (-lzip)

SYNOPSIS

       #include <zip.h>

       int zip_set_default_password(struct zip *archive, const char *password);

DESCRIPTION

       The  zip_set_default_password  function	sets  the  default password used when accessing encrypted files.  If password is NULL, the default
       password is unset.

       If you prefer a different password for single files, use zip_fopen_encrypted(3) instead of zip_fopen(3).  Usually, however, the same  pass-
       word is used for every file in an zip archive.

RETURN VALUES

       Upon successful completion 0 is returned.  Otherwise, -1 is returned and the error information in archive is set to indicate the error.

ERRORS

       zip_set_default_password fails if:

	      [ZIP_ER_MEMORY]
		  Required memory could not be allocated.

SEE ALSO

       libzip(3), zip_fopen(3), zip_fopen_encrypted(3)
