filenameGetExtension()

char * filenameGetExtension

(

char *

s

)

Get the last extension of a filename.

Returns

Pointer to the filename extension starting with '.', or NULL if no extension is found.

Parameters

s	Pointer to string; string is not edited here.

  if(s==NULL || strlen(s)<1) return((char*)NULL);
  /* Identify path */
  char *pptr=strrchr(s, '/'); if(pptr==NULL) pptr=strrchr(s, '\\');
  if(pptr==NULL) pptr=s; else pptr++;
  /* Search for the last '.' after the path */
  char *cptr=strrchr(pptr, '.'); if(cptr==NULL) return(cptr);
  /* If filename starts with '.', that is not counted as extension */
  if(strlen(pptr)==strlen(cptr)) return((char*)NULL);
  return(cptr);

(

char *

s

)

Get all extensions of a filename.

Extension(s) in pathname are not searched for. Note that pointer points to the original string.

Returns

  if(pptr==NULL) pptr=s; else pptr++;
  /* Search for the last '.' after the path, ignoring first character
     in case filename starts with '.' */
  char *cptr=strchr(pptr+1, '.');
  return(cptr);
