ISO_C_BINDING
The intrinsic module provides a set of named constants and procedures that can assist you in programming with mixed languages.
Use the intrinsic module with:
USE, INTRINSIC::ISO_C_BINDING
You have two groups of named constants included in this intrinsic module:
- Constants that hold kind type parameter values for intrinsic types.
- Constants that and those that provide a Fortran equivalent to some of the C special characters.
These constants include:
Named Constant |
C Definition |
Value |
---|---|---|
C_NULL_CHAR |
null character |
'\0' |
C_ALERT |
alert |
'\a' |
C_BACKSPACE |
backspace |
'\b' |
C_FORM_FEED |
form feed |
'\f' |
C_NEW_LINE |
new line |
'\n' |
C_CARRIAGE_RETURN |
carriage return |
'\r' |
C_HORIZONTAL_TAB |
horizontal tab |
'\t' |
C_VERTICAL_TAB |
vertical tab |
'\v' |
The procedures included in ISO_C_BINDING are all generic, not specific. Aside from C_F_POINTER and C_F_PROCPOINTER, all of the procedures are pure. They include:
C_ASSOCIATED
C_F_POINTER
C_F_PROCPOINTER
C_FUNLOC
C_LOC
C_SIZEOF
Additionally, ISO_C_BINDING includes the following derived types to interoperate with C pointers:
C_PTR
C_FUNPTR
C_NULL_PTR
C_NULL_FUNPTR
