Tenemos que tener en cuenta que los dispositivos difieren entre <trademark class=\"registered\">Linux</trademark> y FreeBSD, por lo que se debe tener cuidado para que la emulación de ioctl funcione correctamente. El manejo de ioctl se implementa en <filename>linux_ioctl.c</filename>, donde <function>linux_ioctl</function> la función está definida. Esta función simplemente itera sobre conjuntos de manejadores ioctl para encontrar un manejador que implemente un comando dado. El syscall ioctl tiene tres parámetros, el descriptor de archivo, el comando y un argumento. El comando es un número de 16 bits, que en teoría se divide en 8 bits altos que determinan la clase del comando ioctl y 8 bits bajos, que son el comando real dentro del conjunto dado. La emulación aprovecha esta división. Implementamos controladores para cada conjunto, como <function>sound_handler</function> o <function>disk_handler</function>.Cada controlador tiene un comando máximo y un comando mínimo definido, que se utiliza para determinar qué controlador se utiliza. Hay leves problemas con este enfoque porque <trademark class=\"registered\">Linux</trademark> no usa la división de conjuntos de manera consistente, por lo que a veces los ioctls de un conjunto diferente están dentro de un conjunto al que no deberían pertenecer (ioctls genéricos SCSI dentro del conjunto cdrom, etc.). FreeBSD actualmente no implementa muchos <trademark class=\"registered\">Linux</trademark>ioctls (en comparación con NetBSD, por ejemplo) pero el plan es portarlos de NetBSD. La tendencia es usar <trademark class=\"registered\">Linux</trademark> ioctls incluso en los controladores nativos de FreeBSD debido a la fácil migración de las aplicaciones.", "id": 93295, "action_name": "New translation", "url": "https://translate-dev.freebsd.org/api/changes/93295/?format=api" }, { "unit": "https://translate-dev.freebsd.org/api/units/26622/?format=api", "component": "https://translate-dev.freebsd.org/api/components/freebsd-doc/articles_linux-emulation/?format=api", "translation": "https://translate-dev.freebsd.org/api/translations/freebsd-doc/articles_linux-emulation/es/?format=api", "user": "https://translate-dev.freebsd.org/api/users/Aaron/?format=api", "author": "https://translate-dev.freebsd.org/api/users/Aaron/?format=api", "timestamp": "2020-12-17T19:59:27.690176Z", "action": 5, "target": "Depuración", "id": 93296, "action_name": "New translation", "url": "https://translate-dev.freebsd.org/api/changes/93296/?format=api" }, { "unit": "https://translate-dev.freebsd.org/api/units/26623/?format=api", "component": "https://translate-dev.freebsd.org/api/components/freebsd-doc/articles_linux-emulation/?format=api", "translation": "https://translate-dev.freebsd.org/api/translations/freebsd-doc/articles_linux-emulation/es/?format=api", "user": "https://translate-dev.freebsd.org/api/users/Aaron/?format=api", "author": "https://translate-dev.freebsd.org/api/users/Aaron/?format=api", "timestamp": "2020-12-17T19:59:37.237101Z", "action": 5, "target": "Cada llamada al sistema debería ser depurable.

Due to this, there is no general concept of thread ID shared between kernel and userspace. Of course, both threading libraries implement the pthread thread ID API. Every kernel thread (as described by <literal>struct thread</literal>) has td tid identifier but this is not directly accessible from userland and solely serves the kernel's needs. It is also used for 1:1 threading library as pthread's thread ID but handling of this is internal to the library and cannot be relied on.", "id": 106091, "action_name": "Source string changed", "url": "https://translate-dev.freebsd.org/api/changes/106091/?format=api" }, { "unit": "https://translate-dev.freebsd.org/api/units/229217/?format=api", "component": "https://translate-dev.freebsd.org/api/components/freebsd-doc/articles_linux-emulation/?format=api", "translation": "https://translate-dev.freebsd.org/api/translations/freebsd-doc/articles_linux-emulation/pt_BR/?format=api", "user": null, "author": null, "timestamp": "2021-01-09T14:33:01.924962Z", "action": 30, "target": "As there is a difference in view as what to the idea of a process ID and thread ID is between FreeBSD and <trademark class=\"registered\">Linux</trademark> we have to translate the view somehow.
