Getting the Length of a String in a Memory File Row

To find out the length of a string in a memory file row, call the memory file row length function, mf_rowlen():

int mf_rowlen(mf_row, mfp)

int mf_row;

/* Row to find length of string

*/

MFILEPTR mfp;

/* Memory file to access

*/

This length does not include space for the null terminator at the end of the string.
