Input Parameters

Name	Type	Description
n	FORTRAN: INTEGER C: const int*	FORTRAN: The number of characters in `ca` and `cb` to be compared. C: Pointer to the number of characters in `ca` and `cb` to be compared.
ca, cb	FORTRAN: CHARACTER() C: const char*	Specify two character strings of length at least `n` to be compared. Only the first `n` characters of each string will be accessed.

Description

FORTRAN: INTEGER

C: const int*

FORTRAN: The number of characters in ca and cb to be compared.

C: Pointer to the number of characters in ca and cb to be compared.

ca, cb

FORTRAN: CHARACTER*(*)

C: const char*

Specify two character strings of length at least n to be compared. Only the first n characters of each string will be accessed.

Output Parameters

Name	Type	Description
val	FORTRAN: LOGICAL C: int	FORTRAN: Result of the comparison. .TRUE. if `ca` and `cb` are equivalent except for the case, and .FALSE. otherwise. The function also returns .FALSE. if len(`ca`) or len(`cb`) is less than `n`. C: Result of the comparison. Non-zero if `ca` and `cb` are equivalent except for the case, and zero otherwise.

val

FORTRAN: LOGICAL

C: int

FORTRAN: Result of the comparison. .TRUE. if ca and cb are equivalent except for the case, and .FALSE. otherwise. The function also returns .FALSE. if len(ca) or len(cb) is less than n.

C: Result of the comparison. Non-zero if ca and cb are equivalent except for the case, and zero otherwise.

Description

This logical function tests if the first n letters of one string are the same as the first n letters of another string, regardless of the case.
