Summary
NOTE: The TAL or pTAL syntax for this procedure is declared only in the EXTDECS0 file.
The PROCESS_SPAWN_ procedure creates a new Open System Services (OSS) process and,
optionally, assigns a number of process attributes. You can use this procedure to create only OSS
processes, although you can call it from either a Guardian process or an OSS process. To create
a Guardian process, call the PROCESS_LAUNCH_ procedure.
The PROCESS_SPAWN_ procedure can be used to create a 32-bit or 64-bit OSS process when
called by a Guardian process or a 32-bit OSS process.
The PROCESS_SPAWN_ procedure cannot be called unconditionally from a 64-bit OSS process.
However, this procedure can be called by a 64-bit process in a mixed-mode programming
environment if the passed parameters are allocated from 32-bit addressable memory using
malloc32(). For more information, see the 64-bit Considerations (page 1115).
DEFINEs can be propagated to the new process. The DEFINEs can come from the caller's context
or from a buffer of DEFINEs saved by the DEFINESAVE procedure.
PROCESS_SPAWN_ differs from the OSS functions that create OSS processes in these ways:
• You can specify that the new process be created in either a waited or nowait manner. When
it is created in a waited manner, identification for the new process is returned directly to the
PROCESS_SPAWN_ Procedure 1095
