Deleting Rows in a Memory File

A row of a memory file can be deleted by the memory file row delete function, mf_rowdel():

void mf_rowdel(mf_row, mfp)

int mf_row;

/* Row to delete

*/

MFILEPTR mfp;

/* Memory file to delete string in

*/

Memory allocated for the specified row will be released. All file rows below the specified row will be moved up one row. Memory file parameters are adjusted.

Caution: Deleting rows near the beginning of long memory files requires substantial computing time. Pointers to the contents of every row below the specified row must be moved.

Error handling for this function is identical to that for mf_rowrpl() except that a FILETOOBIG error cannot occur.
