#include <fcntl.h>

int wsreg_can_access_registry(int access_flag);

DESCRIPTION

The wsreg_can_access_registry() function is used to determine what access, if any, an application has to the product install registry.

The access_flag argument can be one of the following:

O_RDONLY Inquire about read only access to the registry.

O_RDWR Inquire about modify (read and write) access to the registry.

RETURN VALUES

The wsreg_can_access_registry() function returns non-zero if the specified access level is permitted. A return value of 0 indicates the specified access level is not permitted.

EXAMPLES

Example 1: Initialize the registry and determine if access to the registry is permitted.

#include <fcntl.h>
#include <wsreg.h>

int main(int argc, char **argv)
{
    int result;
    if (wsreg_initialize(WSREG_INIT_NORMAL, NULL)) {
        printf("conversion recommended, sufficient access denied\n");
    }

    if (wsreg_can_access_registry(O_RDONLY)) {
        printf("registry read access granted\n");
    } else {
        printf("registry read access denied\n");
    }

    if (wsreg_can_access_registry(O_RDWR)) {
        printf("registry read/write access granted\n");
    } else {
        printf("registry read/write access denied\n");
    }
}
