# CONFIG_SEM_PREALLOCHOLDERS: This setting is only used if priority |
|
# inheritance is enabled. It defines the maximum number of |
|
# different threads (minus one) that can take counts on a |
|
# semaphore with priority inheritance support. This may be |
|
# set to zero if priority inheritance is disabled OR if you |
|
# are only using semaphores as mutexes (only one holder) OR |
|
# if no more than two threads participate using a counting |
|
# semaphore. |
|
# CONFIG_SEM_NNESTPRIO. If priority inheritance is enabled, |
|
# then this setting is the maximum number of higher priority |
|
# threads (minus 1) than can be waiting for another thread |

|
# a semaphore. |

|
# three file descriptors (stdin, stdout, stderr) by task_create() |

|
# and stderr. |
|
# CONFIG_SDCLONE_DISABLE. Disable cloning of all socket |
|
# desciptors by task_create() when a new task is started. If |
