mtext_character − Search a character in an M−text.
int mtext_character (MText * mt, int from, int to, int c)
Search a character in an M−text. The mtext_character() function searches M−text mt for character c. If from is less than to, the search begins at position from and goes forward but does not exceed (to − 1). Otherwise, the search begins at position (from − 1) and goes backward but does not exceed to. An invalid position specification is regarded as both from and to being 0.
If c is found, mtext_character() returns the position of its first occurrence. Otherwise it returns −1 without changing the external variable merror_code. If an error is detected, it returns −1 and assigns an error code to the external variable merror_code.
