mtext_prop_range(3m17n) [debian man page]

mtext_prop_range(3m17n) 					 The m17n Library					   mtext_prop_range(3m17n)

NAME

       mtext_prop_range - Find the range where the value of a text property is the same.

SYNOPSIS

       int mtext_prop_range (MText * mt, MSymbol key, int pos, int * from, int * to, int deeper)

DESCRIPTION

       Find the range where the value of a text property is the same. The mtext_prop_range() function investigates the extent where all characters
       have the same value for a text property. It first finds the value of the property specified by key of the character at pos in M-text mt.
       Then it checks if adjacent characters have the same value for the property key.	The beginning and the end of the found range are stored to
       the variable pointed to by from and to.	The character position stored in from is inclusive but that in to is exclusive; this fashion is
       compatible with the range specification in the mtext_put_prop() function, etc.

       If deeper is not 0, not only the topmost but also all the stacked properties whose key is key are compared.

       If from is NULL, the beginning of range is not searched for. If to is NULL, the end of range is not searched for.

RETURN VALUE

       If the operation was successful, mtext_prop_range() returns the number of values the property key has at pos. Otherwise it returns -1 and
       assigns an error code to the external variable merror_code.

ERRORS

	   MERROR_RANGE, MERROR_SYMBOL

NAME

       mtext_put_prop - Set a text property.

SYNOPSIS

       int mtext_put_prop (MText * mt, int from, int to, MSymbol key, void * val)

DESCRIPTION

       Set a text property. The mtext_put_prop() function sets a text property to the characters between from (inclusive) and to (exclusive) in
       M-text mt.  key and val specify the key and the value of the text property. With this function,

			    FROM		   TO
       M-text: |<------------|-------- MT ---------|------------>|
       PROP  :	<------------------ OLD_VAL -------------------->

       becomes

			    FROM		   TO
       M-text: |<------------|-------- MT ---------|------------>|
       PROP  :	<-- OLD_VAL-><-------- VAL -------><-- OLD_VAL-->

RETURN VALUE

	   If the operation was successful, mtext_put_prop() returns 0. Otherwise it returns -1 and assigns an error code to the external variable
	   merror_code.

ERRORS

	   MERROR_RANGE, MERROR_SYMBOL
