int mtext_character (MText * mt, int from, int to, int c)DESCRIPTION¶
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.RETURN VALUE¶
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 .
