 NAMEmtext_character - SYNOPSISint mtext_character (MText * mt, int from, int to, int c) DESCRIPTIONSearch 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. RETURN VALUEIf 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.
