Locate an m-text in a specific range of another.
int mtext_search (MText * mt1, int from, int to, MText * mt2)
Locate an M-text in a specific range of another. The mtext_search() function searches for the first occurrence of M-text mt2 in M-text mt1 in the region from and to while ignoring difference of the text properties. If from is less than to, the forward search starts from from, otherwise the backward search starts from to.
If mt2 is found in mt1, mtext_search() returns the position of the first occurrence. Otherwise it returns -1. If mt2 is empty, it returns 0.
