Function Documentation
◆ add_regvar()
idaman int ida_export add_regvar | ( | func_t * | pfn, |
ea_t | ea1, | ||
ea_t | ea2, | ||
const char * | canon, | ||
const char * | user, | ||
const char * | cmt | ||
) |
Define a register variable.
- Parameters
-
pfn function in which the definition will be created ea1,ea2 range of addresses within the function where the definition will be used canon name of a general register user user-defined name for the register cmt comment for the definition
◆ find_regvar() [1/2]
idaman regvar_t *ida_export find_regvar | ( | func_t * | pfn, |
ea_t | ea1, | ||
ea_t | ea2, | ||
const char * | canon, | ||
const char * | user | ||
) |
Find a register variable definition (powerful version).
One of 'canon' and 'user' should be nullptr. If both 'canon' and 'user' are nullptr it returns the first regvar definition in the range.
- Parameters
-
pfn function in question ea1,ea2 range of addresses to search. ea1==BADADDR means the entire function canon name of a general register user user-defined name for the register
- Returns
- nullptr-not found, otherwise ptr to regvar_t
◆ find_regvar() [2/2]
Find a register variable definition.
- Parameters
-
pfn function in question ea current address canon name of a general register
- Returns
- nullptr-not found, otherwise ptr to regvar_t
◆ has_regvar()
|
inline |
Is there a register variable definition?
- Parameters
-
pfn function in question ea current address
◆ rename_regvar()
Rename a register variable.
- Parameters
-
pfn function in question v variable to rename user new user-defined name for the register
◆ set_regvar_cmt()
Set comment for a register variable.
- Parameters
-
pfn function in question v variable to rename cmt new comment
◆ del_regvar()
idaman int ida_export del_regvar | ( | func_t * | pfn, |
ea_t | ea1, | ||
ea_t | ea2, | ||
const char * | canon | ||
) |
Delete a register variable definition.
- Parameters
-
pfn function in question ea1,ea2 range of addresses within the function where the definition holds canon name of a general register
