Specifies the process whose address space contains the module for which information is required. Identifies the module. The module ID is returned when the module is first loaded. Points to a buffer into which the information is returned. Specifies the size of the info buffer, in bytes. Specifies the number of bytes returned into the info buffer.
The ldr_inq_module() function returns information about a specified module contained within the address space of the specified process into the variable pointed to by the info parameter. The info_size parameter is the size of the buffer provided. The number of bytes filled in (that is, the returned structure size) is returned in the buffer pointed to by the ret_size parameter.
To obtain the unique process identifier for the current process, use the
To obtain the unique process identifier for the kernel, use the call: ldr_process_t ldr_kernel_process();
This function is currently only implemented for the current process and the kernel.
Upon successful completion, the function returns a value of 0 (zero). If the operation fails, the function returns a negative error value and sets errno to indicate the error.
If the ldr_inq_module() function fails, errno may be set to one of the following values: The specified module ID is not valid. The process identifier is not valid.
In addition, errors pertaining to the IPC mechanism can be returned.
