The * 00063 * International Union of Crystallography holds the Copyright on * 00064 * the CIF, and has applied for Patents on the STAR File syntax * 00065 * which is the basis for the CIF format. * 00066 * * 00067 * It is a principal objective of the IUCr to promote the use of * 00068 * CIF for the exchange and storage of scientific data. The IUCr's * 00069 * sponsorship of the CIF development was motivated by its * 00070 * responsibility to its scientific journals, which set the * 00071 * standards in crystallographic publishing. The IUCr intends that * 00072 * CIFs will be used increasingly for electronic submission of * 00073 * manuscripts to these journals in future. The IUCr recognises * 00074 * that, if the CIF and the STAR File are to be adopted as a means * 00075 * for universal data exchange, the syntax of these files must be * 00076 * strictly and uniformly adhered to. Even small deviations from * 00077 * the syntax would ultimately cause the demise of the universal * 00078 * file concept. Through its Copyrights and Patents the IUCr has * 00079 * taken the steps needed to ensure strict conformance with this * 00080 * syntax. * 00081 * * 00082 * The IUCr policy on the use of the CIF and STAR File processes is * 00083 * as follows: * 00084 * _________________________________________________________________ * 00085 * * 00086 * * 1 CIFs and STAR Files may be generated, stored or transmitted, * 00087 * without permission or charge, provided their purpose is not * 00088 * specifically for profit or commercial gain, and provided that * 00089 * the published syntax is strictly adhered to. * 00090 * * 2 Computer software may be developed for use with CIFs or STAR * 00091 * files, without permission or charge, provided it is distributed * 00092 * in the public domain. This condition also applies to software * 00093 * for which a charge is made, provided that its primary function * 00094 * is for use with files that satisfy condition 1 and that it is * 00095 * distributed as a minor component of a larger package of * 00096 * software. * 00097 * * 3 Permission will be granted for the use of CIFs and STAR Files * 00098 * for specific commercial purposes (such as databases or network * 00099 * exchange processes), and for the distribution of commercial * 00100 * CIF/STAR software, on written application to the IUCr Executive * 00101 * Secretary, 2 Abbey Square, Chester CH1 2HU, England. The * 00102 * nature, terms and duration of the licences granted will be * 00103 * determined by the IUCr Executive and Finance Committees. * 00104 * * 00105 * _________________________________________________________________ * 00106 * * 00107 * In summary, the IUCr wishes to promote the use of the STAR File * 00108 * concepts as a standard universal data file. It will insist on * 00109 * strict compliance with the published syntax for all * 00110 * applications. To assist with this compliance, the IUCr provides * 00111 * public domain software for checking the logical integrity of a * 00112 * CIF, and for validating the data name definitions contained * 00113 * within a CIF. Detailed information on this software, and the * 00114 * associated dictionaries, may be obtained from the IUCr Office at * 00115 * 5 Abbey Square, Chester CH1 2HU, England. * 00116 **********************************************************************/ 00117 00118 #ifdef __cplusplus 00119 00120 extern "C" { 00121 00122 #endif 00123 00124 #include <stdlib.h> 00125 #include <stdio.h> 00126 #include <string.h> 00127 #include <limits.h> 00128 00129 #include "cbf_byte_offset.h" 00130 00131 00132 /* Compress and array with the byte-offset algorithm */ 00133 00134 int cbf_compress_byte_offset (void *source, 00135 size_t elsize, 00136 int elsign, 00137 size_t nelem, 00138 unsigned int compression, 00139 cbf_file *file, 00140 size_t *compressedsize, 00141 int *storedbits) 00142 { 00143 fprintf (stderr, 00144 "\n*** Byte-Offset Algorithm Not Implemented Yet -- Abort ***\n"); 00145 00146 exit (1); 00147 00148 return 1; 00149 } 00150 00151 00152 /* Decompress an array with the byte-offset algorithm */ 00153 00154 int cbf_decompress_byte_offset (void *destination, 00155 size_t elsize, 00156 int elsign, 00157 size_t nelem, 00158 size_t *nelem_read, 00159 unsigned int compression, 00160 cbf_file *file) 00161 { 00162 fprintf (stderr, 00163 "\n*** Byte-Offset Algorithm Not Implemented Yet -- Abort ***\n"); 00164 00165 exit (1); 00166 00167 return 1; 00168 } 00169 00170 00171 #ifdef __cplusplus 00172 00173 } 00174 00175 #endif
