DESCRIPTION

XmTextFindString locates the beginning position of a specified text string. This routine searches forward or backward for the first occurrence of the string starting from the given start position. If it finds a match, the function returns the position of the first character of the string in position. If the match string begins at the current position, this routine returns the current position.

position

Specifies the pointer in which the first character position of the string match is returned. This is an integer number of characters from the beginning of the buffer. The first character position is 0 (zero). If the function returns False, this value is undefined.
