fopen_s() function defined in ISO/IEC TR 24731-1 |
fopen() function. However, like fopen(), {{fopen_s()}} function is designed to improve the security of the {{fopen()}} function \[[ISO/IEC TR 24731-1:2007|AA. C References#SO/IEC TR 24731-1-2007]\]. However, like {{fopen()}}, {{fopen_s()}} provides no mechanism to determine if an existing file has been opened for writing or a new file has been created. |
