# mtext\_compare(3m17n)

## NAME

mtext\_compare -

## SYNOPSIS

int **mtext\_compare** (**MText** \* *mt1*, int *from1*, int *to1*, **MText** \* *mt2*, int *from2*, int *to2*)

## DESCRIPTION

Compare specified regions of two M-texts. The **mtext\_compare()** function compares two M-texts **mt1** and **mt2**, character-by-character. The compared regions are between **from1** and **to1** in **mt1** and **from2** to **to2** in MT2. **from1** and **from2** are inclusive, **to1** and **to2** are exclusive. **from1** being equal to **to1** (or **from2** being equal to **to2**) means an M-text of length zero. An invalid region specification is regarded as both **from1** and **to1** (or **from2** and **to2**) being 0.

## RETURN VALUE

This function returns 1, 0, or -1 if **mt1** is found greater than, equal to, or less than **mt2**, respectively. Comparison is based on character codes. \
