c = ( strlen(replace) – search_size )*c + strlen(subject);

//New subject with new size
new_subject = malloc( c );

Hallo
This source is listed in Google so please correct

If replace is shorter then search you get a negativ size –> segfault
Check for nothing to replace.
Free the old subject.

By the way, i think strcat is easier then the strncpy way.

In reply to wakyelmadno. why do we need to insert that. inserting new_subject='' in line 63 will erase the new string.

Thanks for the function.

Buf we need insert this new_subject[p-old] = ”; in line 53 and new_subject[c][/c]=”; in line 63
