How to add the attribute to odm if it contains negative value?
Hi All,

I am trying to add odm_wait attribute to CuAt programatically using putattr(&pCuAt).

I was able to add when the odm_wait has positive value [i.e 0]. But, I am facing issues when the odm_wait has negative value [i.e-1]

As per IBM, these are the odm_wait possible values
Code:
#define ODM_WAIT   -1  /* Wait forever                               */
#define ODM_NOWAIT  0  /* Return immediately if lock cannot be granted */

This is the piece of code from my program.

Code:
strcpy(pCuAt.name, hdiskname);
                        strcpy(pCuAt.attribute, "odm_wait");
                        sprintf(pCuAt.value,"%d", odm_wait);
                        strcpy(pCuAt.type, "R");
                        strcpy(pCuAt.generic, "DU");
                        strcpy(pCuAt.rep, "nr");
                        pCuAt.nls_index=120;
                        if (putattr(&pCuAt) == -1)
                                printf("error: could not add attribute <odm_wait> to odm \n");
                        else
				printf("Notice : %s odm_wait attribute is added successfully: \n", hdiskname);

My program is running without any issue in both the cases [-1,0] and also I am not getting any error when the odm_wait attribute is -1.
But, when odm_wait attribute is -1, it is not actually adding the attribute to ODM.

When I try to access that value it is not displaying any records.
Code:
bash-3.2# odmget -q"name= hdisk7 and attribute=odm_wait" CuAt
bash-3.2#
bash-3.2#

Do we need to follow any other way to add the attribute when it has negative value?

Please help me to figure out the issue.

Many Thanks

glgetattriblocation

GLGETATTRIBLOCATION(3G) 					   OpenGL Manual					   GLGETATTRIBLOCATION(3G)

NAME

       glGetAttribLocation - Returns the location of an attribute variable

C SPECIFICATION

       GLint glGetAttribLocation(GLuint program, const GLchar *name);

PARAMETERS

       program
	   Specifies the program object to be queried.

       name
	   Points to a null terminated string containing the name of the attribute variable whose location is to be queried.

DESCRIPTION

       glGetAttribLocation queries the previously linked program object specified by program for the attribute variable specified by name and
       returns the index of the generic vertex attribute that is bound to that attribute variable. If name is a matrix attribute variable, the
       index of the first column of the matrix is returned. If the named attribute variable is not an active attribute in the specified program
       object or if name starts with the reserved prefix "gl_", a value of -1 is returned.

       The association between an attribute variable name and a generic attribute index can be specified at any time by calling
       glBindAttribLocation(). Attribute bindings do not go into effect until glLinkProgram() is called. After a program object has been linked
       successfully, the index values for attribute variables remain fixed until the next link command occurs. The attribute values can only be
       queried after a link if the link was successful.  glGetAttribLocation returns the binding that actually went into effect the last time
       glLinkProgram() was called for the specified program object. Attribute bindings that have been specified since the last link operation are
       not returned by glGetAttribLocation.

ERRORS

       GL_INVALID_OPERATION is generated if program is not a value generated by OpenGL.

       GL_INVALID_OPERATION is generated if program is not a program object.

       GL_INVALID_OPERATION is generated if program has not been successfully linked.

ASSOCIATED GETS

       glGetActiveAttrib() with argument program and the index of an active attribute

       glIsProgram()
