Lb libcSYNOPSIS
In sys/param.h In sys/linker.h Ft int Fn kldstat int fileid struct kld_file_stat *statDESCRIPTION
The Fn kldstat system call writes the info for the file referred to by Fa fileid into Fa stat .struct kld_file_stat { int version; /* set to sizeof(linker_file_stat) */ char name[MAXPATHLEN]; int refs; int id; caddr_t address; /* load address */ size_t size; /* size in bytes */ char pathname[MAXPATHLEN]; };
- version
- This field is set to the size of the structure mentioned above by the code calling Fn kldstat , and not Fn kldstat itself.
- name
- The name of the file referred to by Fa fileid .
- refs
- The number of modules referenced by Fa fileid .
- id
- The id of the file specified in Fa fileid .
- address
- The load address of the kld file.
- size
- The size of the file.
- pathname
- The full name of the file referred to by Fa fileid , including the path.
RETURN VALUES
Rv -std kldstatERRORS
The information for the file referred to by Fa fileid is filled into the structure pointed to by Fa stat unless:- Bq Er ENOENT
- The file was not found (probably not loaded).
- Bq Er EINVAL
- The version specified in the Fa version field of stat is not the proper version. You would need to rebuild world, the kernel, or your application, if this error occurs, given that you did properly fill in the Fa version field.
- Bq Er EFAULT
- There was a problem copying one, some, or all of the fields into Fa stat in the copyout(9) function.

The pathname many not be accurate if the file system mounts have changed since the module was loaded, or if this function is called within a chrooted environment.Contenus ©2006-2024 Benjamin Poulain
