Return codes

When the Latch_Create service returns control to your program, return_code contains a hexadecimal return code. The following table identifies return codes in hexadecimal and decimal (in parentheses), the equate symbol associated with each return code, the meaning of each return code, and a recommended action:

Table 1. ISGLCRT Return Codes
Return code and Equate symbol	Meaning and Action
00 (0) ISGLCRT_SUCCESS	Meaning: The Latch_Create service completed successfully. Action: None required.
04 (4) ISGLCRT_DUPLICATE_NAME	Meaning: The specified latch_set_name already exists, and is associated with a latch set that was created by a program running in the current primary address space. The latch manager does not create a new latch set. Action: To create a new latch set, specify a unique name on the latch_set_name parameter, then call the Latch_Create service again. Otherwise, continue processing with the returned latch set token.
10 (16) ISGLCRT_NO_STORAGE	Meaning: Environmental error. Not enough storage was available to contain the requested number of latches. The latch manager does not create a new latch set. Action: Specify a smaller value on the number_of_latches parameter.
