If no such character exist in the string, the string's end is returned. .PP The comparison is case-insensitive. .SH RETURN VALUE The .BR libsimple_strcasechr () function returns the pointer .I s with a minimal offset such that .IR tolower(*r)==tolower(c) , where .I r is the returned pointer, if no such offset exists, it returns .IR NULL . .SH ERRORS The .BR libsimple_strcasechr () function cannot fail. .SH ATTRIBUTES For an explanation of the terms used in this section, see .BR attributes (7). .TS allbox; lb lb lb l l l.
