Cold Help System: Programming: ColdC Reference Manual: Functions: String: stridx()

INTEGER stridx(STRING str, STRING what[, INTEGER origin])

This function returns the position in str where what exists--starting from origin--or a zero if it does not exist. If origin is not specified it will default to 1. The origin represents where to start searching in the string. If it is a positive number it starts that many elements into the string. If it is a negative number it starts that many elements from the end of the string, and searches backwards--from the end of the string to the start. Examples:

stridx("this test ok", "e")
=> 7

stridx("this test ok", "t", -1)
=> 9

stridx("this test ok", "t", -5)
=> 6

stridx("this test ok", "alf")
=> 0
