Function Documentation

filenameGetExtension()

char * filenameGetExtension

(

const char *

s

)

Get the last extension of a file name.

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

See also

filenameGetExtensions, filenameRmExtension, strTrimLeft

Returns

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

Parameters

s	Pointer to string; string is not edited here.

Definition at line 178 of file filename.c.

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

filenameGetExtensions()

char * filenameGetExtensions

(

const char *

s

)

Get all extensions of a file name.

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

filenameGetExtension, filenameRmExtensions, strTrimLeft

Returns

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

Parameters

s	Pointer to string; string is not edited here.

  if(s==NULL || strnlen(s, 1)<1) return((char*)NULL);
  /* Identify path */
  char *pptr=strrchr(s, '/'); if(pptr==NULL) pptr=strrchr(s, '\\');
  if(pptr==NULL) pptr=(char*)s; else pptr++;
  /* Search for the last '.' after the path, ignoring first character in case file name starts with '.' */
  char *cptr=strchr(pptr+1, '.');
  return(cptr);

filenameRmFile()

void filenameRmFile

(

char *

s
