Searching for a String Within a Memory File

You can search through a memory file for a string. You can start the search at the top of the memory file or at some other point in the memory file. To search for a string, use one of the two memory file search functions, mf_search() and mf_txtrow():

int mf_search(stp, beg_row, mfp)

UCHAR *stp;

/* String to search for

*/

int beg_row;    

/* Row to begin search at

*/

MFILEPTR mfp;

int mf_txtrow(stp, mfp)

/* Memory file to search

*/

UCHAR *stp;

/* String to search for 

*/

MFILEPTR mfp;

/* Memory file to search 

*/

These functions return the number of the row whose beginning matches the specified string. mf_txtrow() begins searching on line 0; mf_search() allows you to specify the line number to begin searching on.
